Frequently Asked Questions - Superman II Maxi Dial YEMA

How do I wind the Yema Superman II Maxi Dial?

To wind the watch manually, unscrew the crown (turn counterclockwise until it pops out) to position 1. Turn the crown clockwise (about 30-40 rotations) until you feel resistance. Do not overwind. Push the crown back in and screw down tightly.

Is the watch suitable for diving?

Yes, the Superman II Maxi Dial has a water resistance of 300 meters (1000 feet), making it suitable for professional diving. Ensure the crown is fully screwed down before any water exposure.

How do I set the date and time?

Unscrew the crown to position 2 (first click) to set the date. Turn clockwise to advance the date. Pull to position 3 (second click) to set the time. For accurate AM/PM setting, advance the date past midnight, then set the correct time.

What movement does this watch use?

It uses the in-house Yema Caliber 2000 automatic movement, with a frequency of 28,800 bph (4 Hz) and a power reserve of approximately 38 hours.

How do I adjust the metal bracelet?

The bracelet uses screw pins. Use a small screwdriver to remove the screws from the links you want to remove. Work on both sides equally. Refer to the manual for exact link removal guidelines.

What is the accuracy of the movement?

The Yema Caliber 2000 is regulated to run within -10 to +20 seconds per day. Actual performance may vary depending on wearing habits and position.

How often should I service the watch?

It is recommended to service the movement every 3 to 5 years to maintain accuracy and water resistance. Always use an authorized Yema service center.

Can I change the bezel insert?

The bezel insert is not designed for user replacement. If damaged, contact Yema service for replacement. The bezel itself can be rotated unidirectionally for dive timing.

What is the warranty period?

Yema offers a 2-year international warranty from the date of purchase against manufacturing defects. Keep your proof of purchase and warranty card.

How do I care for the sapphire crystal?

Sapphire crystal is highly scratch-resistant but can chip on hard impact. Clean with a soft, lint-free cloth. Avoid abrasive cleaners.

USER MANUAL Superman II Maxi Dial YEMA

Your YEMA watch is equipped with a screw-down crown. A screw-down crown ensures waterproofness by sealing the crown to the case of the watch.

POSITION B MANUAL WINDING

Your YEMA watch is equipped with a self-winding mechanical movement, this means is wound automatically by wrist movements alone. To ensure optimum winding, wear your watch daily.

Before you first use the watch or if unworned for a long period of time, you will need to wind it manually by unscrewing the crown and then turning it clockwise.

POSITION C RAPID DATE-SETTING

If your YEMA watch is equipped with a date, to adjust the date, unscrew the crown and pull it out to the second notch. Then simply turn it clockwise until the desired date appears in the window. During this operation, your watch will keep running.

IMPORTANT: Do not make date adjustments when the time on the watch reads between the hours of 9:00pm and 3:00am. The reason is that although a date makes its changeover close to midnight, the gears that make that change happen to engage quite a bit earlier. It takes extra time to disengage completely in the aftermath.

TIME SETTING POSITION D

In order to adjust the time, unscrew the crown and pull it out to the last notch. Then turn it in either direction until the hands indicate the correct time. The small seconds hand is stopped during this operation, allowing the time to be set accurately.

BEZEL-LOCK MECHANISM

As an extra safety measure, YEMA developed a proprietary bezel-lock mechanism in the 1960s, which is still used nowadays and brings a unique look to the Superman Collection.

BEZEL FUNCTIONS

The unidirectional rotatable bezel allows precise measurement of dive times. For safety, the bezel rotates counter-clockwise only.

Before beginning your descent, unscrew the crown to POSITION B to unlock the bezel, then turn the bezel until the 12 o'clock triangle marker is opposite to the minute hand. To finish, screw-down the crown to POSITION A.

This indicates the beginning of the dive. The duration of the dive is indicated on the graduation on the bezel by the minute hand.

MAINTENANCE

OF YOUR YEMA WATCH

A YEMA watch requires little maintenance. However, some precautions must be taken to ensure the durability of your YEMA:

• Ensure that the crown is perfectly screwed down after winding up the movement and/or setting the time and the date. Once the crown is fully screwed down against the case, your YEMA watch is guaranteed waterproof.
• Avoid activities that may expose your watch movement to shocks.
• Never use chemicals to clean your YEMA watch. Use a microfibre cloth and wash the metal, rubber, fabric bracelets and waterproof cases from time to time with a soft brush and soapy water. We recommend that you do not use abrasive or corrosive products (solvents, detergents, perfume, etc.).
  · Always rinse your watch with fresh water after it's been exposed to salt water.

BRONZE WATCH MAINTENANCE

YEMA bronze watches develop a darker appearance due to the natural process of patina, they can create a build up of dark and/or greenish coating in areas of the watch depending to the degree of exposure to atmospheric conditions (heat, humidity, pollution) and when used during aquatic activities on the seaside (salty water) and swimming pools (chemicals). Most customers love this, as it adds character to the watch that becomes unique to each wearer.

However, one can easily reverse reverse the patina and bring your bronze watch back to a healthy shine in just a few minutes. To do so, create a paste out of baking soda and lemon juice, apply an even coat of the paste to the bronze watch, then rub it away with a soft toothbrush or cloth after and allow it to sit for 20-30 minutes with the paste still on it. Remove the paste and rinse the watch under warm water. Dry and polish with a cotton cloth ensuring that all of the paste has been removed. If any patina still remains then repeat the process. Your bronze watch will now be cleaned and should look almost as good as new.
