FAQs

What is the movement inside this watch?

It is powered by the Longines calibre L836, a high-beat automatic movement.

Is the sapphire crystal prone to scratching?

No, sapphire crystal is highly scratch-resistant and remains clear under normal wearing conditions.

Can I wear this watch while swimming?

With 50 meters of water resistance, it is not recommended for swimming or diving.

How long is the power reserve?

The watch features a 52-hour power reserve.

Does the watch require battery changes?

No, this is a mechanical automatic watch that winds itself through the movement of your wrist.

What is the benefit of a high-beat movement?

A high-beat movement oscillates at a higher frequency, which generally improves the watch's accuracy and stability.

Troubleshooting

Watch has stopped running

Manually wind the crown clockwise for 20-30 rotations to build up the power reserve.

Watch is gaining or losing significant time

Ensure the watch has not been exposed to strong magnetic fields; if accuracy issues persist, consult an authorized service center for regulation.

Leather strap feels stiff

Leather will naturally soften with regular wear; avoid submerging the strap in water to prevent cracking.

Pros and Cons

Pros

Compact 37mm case size sits comfortably on a variety of wrist sizes
High-beat automatic movement provides exceptional mechanical accuracy
Scratch-resistant sapphire crystal ensures long-term dial clarity

50-meter water resistance is limited for a watch with 'Diver' roots

Setup, Compatibility & Care

To set the time, unscrew (if applicable) or pull the crown to the second position to hack the seconds hand and adjust the time. The black leather strap features a secure buckle that should be checked periodically for signs of wear to ensure the safety of the watch. To maintain the movement's integrity, avoid exposing the watch to extreme magnetic fields, such as high-powered speakers or industrial magnets. Clean the stainless steel case using a soft, dry cloth to remove fingerprints and oils. Avoid using harsh chemicals or abrasive materials on the sapphire crystal or the leather strap, as these can cause permanent damage to the finish.
