UNIDIRECTIONAL ROTATING DIVING BEZEL

An essential feature of all Alpina diving watches is the unidirectional, anti- clockwise, rotating bezel, used to control immersion time. The bezel is fitted with a graduated scale divided into minutes. The bezel’s working principle is both simple and reliable. At the beginning of each immersion, the zero on the bezel must be aligned with the minute hand. A simple glance at the position of the minute hand with respect to the bezel will show the diver at any moment how much time has elapsed since the start of the dive (in minutes). The unidirectional anti-clockwise rotation of the bezel is a safety feature that ensures that any accidental movement of the ring will always cause the remaining diving time to reduce with respect to the effective remaining diving time.

An essential feature of all Alpina diving watches is the bidirectional rotating bezel, used to control immersion time. The bezel is fitted with a graduated scale divided into minutes. The bezel’s working principle is both simple and reliable. At the beginning of each immersion, the zero on the bezel must be aligned with the minute hand. A simple glance at the position of the minute hand with respect to the bezel will show the diver at any moment how much time has elapsed since the start of the dive (in minutes). Our watch is equipped with a screw-down crown so the bidirectional internal bezel cannot move unless the crown is unscrewed. This is a safety feature to avoid any accidental movement of the bidirectional internal bezel that could make the diving time incorrect

MEASUREMENT SCALES

Measurement scales are scales that establish a relation between elapsed time and another variable. The desired information in terms of speed (tachymeter), distance (telemeter) or units (pulsometer, productivity meters) is read off between the central seconds hand of the chronograph and the corresponding scale, over a maximum duration of 60 seconds. For the telemeter, it is possible to make use of the minutes counter by adding 20 km to the distance indicated by the central seconds hand for each minute elapsed.

TACHYMETER SCALES

Only for:
AL-725xARx – AL-727x4NHx

TACHYMETER SCALE USE
Example 1 : calculating the speed of a car. Measure the time it takes the car to cover a distance of 1 km. Read off the speed indicated by the central chronograph seconds hand on the tachymetric scale. In our example, the car is travelling at 90 km/h.
TELEMETER SCALES
Example 2: calculating the distance between your position and an upcoming storm. Start the chronograph when you see the lightning; then stop the chronograph when you hear the thunder. Read off the distance indicated by the central chronograph hand on the telemetric scale. In our example the storm is 5 km away from your position.

360° ROTATING COMPASS BEZEL

Alpina watches featuring a 360° rotating compass bezel can roughly determine directions – a particularly useful feature for orientation sports and other adventure or alpine sports.

**COMPASS USE INSTRUCTIONS ON ALPINER 4 CHRONOGRAPH AND ALPINER 4 GMT***

Precautions in using a compass bezel:

  • Do not use the compass in situations where accuracy is critical. The compass only gives a rough indication of direction.
  • Use the compass where the sun is visible or its location known.
  • Your watch must be set to winter time. If daylight savings time (summer time) is in effect in your area, you must set your watch one hour behind before using the compass bezel.

OPERATING INSTRUCTIONS

IN THE NORTHERN HEMISPHERE

  • Set the “36” (=360°=North) on the rotating compass bezel facing the current time on the 24H ring.
  • While keeping the dial level, point the hour hand in the direction of the sun.
  • Now the compass is activated and you can read the directions on the rotating compass bezel. The 36, 09,18, 27 indicate North, East, South and West, respectively.

Example 1: It is 8 am in your area. Set the n° 36 facing
the 8 on the 24H scale of the dial. Now point the hour
hand (keeping the dial level) in the direction of the sun
and your compass is activated.
Example 2: It is 6 pm in your area. Set the n° 36 facing
the 18 on the 24H scale of the dial. Now point the hour
hand (keeping the dial level) in the direction of the sunand your compass is activated.

IN THE SOUTHERN HEMISPHERE

  • Set the “18” (=180°=South) on the rotating compass bezel facing the current time on the 24H ring.
  • While keeping the dial level, point the hour hand in the direction of the sun.
  • Now the compass is activated and you can read the directions on the rotating compass bezel. The 36, 09,18, 27 indicate North, East, South and West, respectively.

Example 1 : It is 8 am in your area. Set the n° 18 facing the 8 on the 24H scale of the dial. Now point the hour hand (keeping the dial level) in the direction of the sun and your compass is activated.
Example 2: It is 6 pm in your area. Set the n° 18 facing the 18 on the 24H scale of the dial. Now point the hour hand (keeping the dial level) in the direction of the sun and your compass is activated.

When using the Alpiner 4 GMT you can also use the 24H hand to operate the compass. To do this, the 24H hand must indicate your local time.
A) In the northern hemisphere put the “36” (=North) facing the 24H hand. Point the hour hand (keeping the dial level) in the direction of the sun and your compass is activated.
B) In the southern hemisphere put the “18” (=South) facing the 24H hand. Point the hour hand (keeping the dial level) in the direction of the sun and your compass is activated

COMPASS USE INSTRUCTIONS ON SEASTRONG YACHT TIMER

IN THE NORTHERN HEMISPHERE
Set the “S” (=South) on the rotating compass bezel to the middle of the arc between the “60” marker (=12 o’clock) and the hour hand.*
in the AM period, set the “S” to the left of the “60” marker (=12 o’clock) and in the PM period to theight of the “60” marker (=12 o’clock).

  • While keeping the dial level, point the hour hand in the direction of the sun.
  • Now the compass is activated and you can read the directions on the rotating compass bezel. The triangle at “60”, the 90 marker, the S and the 270 marker indicate North, East, South and West, respectively

Example 1: It is 10 am in your area. Set the “S” facing the “5” on the dial (=half way between 12 o’clock and the hour hand). Now point the hour hand (keeping the dial level) in the direction of the sun and your compass is activated.
Example 2 : It is 6 pm in your area. Set the “S” facing the “45” (=3 o’clock) on the dial (=half way between 12 o’clock and 6 o’clock). Now point the hour hand (keeping the dial level) in the direction of the sun and your compass is activated.

ANTI-MAGNETISM

Only for:
AL-525xAQx – AL-760xAQ

Magnetic fields can significantly impact the precision of your watch. There are many sources of magnetic fields, such as mobile phones, iPads, computers, loudspeakers, refrigerators and other electronic devices. The more powerful the magnetic field the higher the impact on your watch. All Alpina watches designated by “4”, i.e. the “Alpiner 4”, are antimagnetic. This means that they have a minimal deviation when exposed to a certain level of magnetic field.
Alpina “4” anti-magnetic watches conform to the international ISO 764 standard which defines the resistance of watches to magnetic fields. According to ISO 764 a watch must resist exposition to a direct current magnetic field of 4,800 A/m. The watch must keep its accuracy to ± 30 seconds/day as measured before the test in order to be recognised as a magneticresistant watch.

WATCH CARE & WARRANTY

TAKING CARE OF YOUR ALPINA WATCH

PLEASE FOLLOW THE BELOW RECOMMENDATIONS, TO ENSURE THAT YOUR ALPINA WATCH WILL SERVE YOU LOYALLY AND WITH EXCELLENCE THROUGHOUT THE YEARS.

  1. Swimming in salt water: take care to rinse your watch with fresh water immediately after your swim.

  2. Magnetism: avoid placing your watch on iPads, computers, loudspeakers, mobile phones or refrigerators. These devices generate powerful magnetic fields that can affect the precision of your watch.

  3. Shocks to the watch: different types of shocks – whether chemical, thermal, physical, magnetic or other – can affect your watch. Take care to avoid them.

  4. Screw-in crown: to prevent water or humidity from entering the case, make sure the crown is always tightly screwed into the case. Do not use chronograph pushers under water.

  5. Normal crown: to prevent humidity from entering the case, make sure the crown is always pushed back in the wearing position. Do not use chronograph pushers under water.

  6. Care and cleaning of metal bracelets, rubber straps and water-resistant metal cases: clean with soapy water and a toothbrush and dry with a soft cloth.

  7. Chemical products: avoid direct contact with chemical cleaning agents, solvents, detergents, cosmetics and other chemical products, as they may damage your case, bracelet or rubber gaskets
    SERVICE AND SERVICE INTERVALS

  8. Temperature: avoid exposure to temperatures greater than 60°C (140°F), or below 0°C (32°F). Also avoid extreme changes in temperature, such as putting the watch in extremely cold water after prolonged exposure to the sun.

  9. Water-resistance: a watch’s water-resistance cannot be guaranteed in all situations or for ever. The water-resistance can be affected by a shock to the crown, the ageing of gaskets (for example, due to the action of chemical products), etc.

Like any other mechanical precision instrument, it is important to service a watch at regular intervals to make sure it performs correctly in time. As a general rule, and depending on how you use your watch and the conditions in which you use it, we advise you to have your watch serviced every 4 to 5 years. You can find the list of our Official Retailers and Service Centres at www.alpinawatches.com

MECHANICAL WATCHES

The balance wheel in an automatic Alpina watch swings 28,800 times an hour and the gear train moves forward 691,200 times in 24 hours. In four years, this represents over one billion impulses!
We advise you to bring your watch every 3-4 years to an official Alpina Retailer or Service Centre, where a trained watchmaker will meticulously inspect it before thoroughly cleaning and lubricating the movement.

WATER-RESISTANCE

The water-resistance rating of your watch was determined and checked when it was manufactured at our workshops. It does not imply a lifetime guarantee against water entering into the watch.

Your watch is water-resistant only when the crown is fully pushed-in against the case. If your watch has a screw-in crown, it must be tightly screwed into the case. Your watch is not water-resistant if the crown is in the winding or time-setting positions. Likewise, pushers should not be operated while the watch is wet or in water.

Ageing and normal day-to-day handling affect the water-resistance of your watch. Avoid temperature extremes (immersing the watch in cold water after a prolonged period in the hot sun) that can damage the gaskets as well as any other shocks – chemical, physical or other – which might compromise the technical integrity of the watch case. We advise you to bring your watch to an Official Alpina Retailer or Service Centre for a water-resistance check every 2-3 years.

LEATHER STRAP CARE

We recommend you adhere to the following indications to keep your leather strap in good condition for as long as possible:

  1. Avoid contact with water and humidity to prevent discolouration and deformation.
  2. Avoid prolonged exposure to the sun to prevent discolouration.
  3. Avoid contact with greasy substances, cosmetic products and any other chemical agent.

Leather is an organic and permeable material and therefore will not last for ever in its original condition. However, if you adopt the steps above it will last for many years. You can replace your leather strap at any Official Alpina Retailer.

ANTI-REFLECTIVE TREATMENT OF THE SAPPHIRE CRYSTAL

The anti-reflective treatment of the sapphire crystal improves the visibility and contrast of your watch’s dial. Normal daily use and wear and tear may cause marks to appear on the coating. These are considered normal and are therefore not covered by the warranty.

GENUINESS

We are often asked to check if a Alpina watch is genuine. Official Alpina retailers attest the genuineness of every Alpina watch and provide expert and dependable after-sales servicing, thanks to their expertise and professional skills, and to specially adapted equipment.

Alpina Watch International S.A. disclaims any relationship to, or responsibility for, any timepiece or other item bearing the Alpina name, brand, logotype or symbol offered for sale by anyone not being an official Alpina retailer.
Purchasing such an item from an unauthorized party

SCREW-IN CROWN

Some Alpina watches have a screw-in crown, which must be unscrewed to change the time or the date. After use, the crown must be pressed against thecase and screwed in tightly. Failure to do so will compromise the water-resistance of your watch.

is therefore at the buyer’s sole risk, particularly in the case of counterfeit or substandard products and in case of products purchased on the Internet. No explicit or implicit warranty or servicing or any other obligation shall ensue for Alpina or for any of its authorized representatives for products sold by unauthorized parties and not accompanied by a duly stamped Alpina international warranty certificate.

For the above reasons and in your own interest, you are invited to acquire only genuine Alpina timepieces available exclusively from a legitimate Alpina official retailer.
