FAQs

What is the 'turtle' nickname referring to?

The nickname comes from the distinctive, rounded, and comfortable shape of the watch case, which resembles a turtle's shell when viewed from the side.

How long does the power reserve last?

The watch features a power reserve of up to 70 hours, meaning it will continue to run for approximately three days without being worn.

Is this watch suitable for scuba diving?

Yes, with a 200m water resistance rating, unidirectional rotating bezel, and screw-down crown, this watch is designed and tested for professional diving.

How do I maintain the water resistance?

Always ensure the crown is fully screwed down or pushed in before any water exposure. Have the water resistance checked periodically by a professional, especially if used for diving.

What makes the 'Lumibrite Pro' special?

Lumibrite Pro is a specially developed luminous material that offers enhanced brightness and longevity in low-light conditions, and it maintains its green color consistently in both light and dark.

Does this watch require a battery?

No, this is an automatic watch powered by the movement of the wearer's wrist. It does not have or require a battery.

Can I change the silicone strap?

Yes, the silicone strap uses standard lug attachments, allowing for replacement with other compatible straps if you wish to change the look or material.

Troubleshooting

Watch has stopped running

Gently shake the watch for about 30 seconds to wind the mainspring. If the watch has been unworn for over 70 hours, the power reserve may be depleted. Manual winding via the crown (if applicable to Calibre 6R35 function for this model) may also be an option.

Date is not changing correctly

Ensure you are not trying to change the date between 9 PM and 3 AM, as this can damage the date-changing mechanism. Set the time to past 3 AM, change the date if needed, and then set the correct time.

Lume is not bright or fading quickly

Luminous materials require exposure to light to 'charge'. Ensure the watch has been exposed to sufficient light. The brightness and duration of the glow depend on the intensity and duration of light exposure.

Condensation under the crystal

This indicates a potential breach in water resistance. Do not operate the crown or buttons. Seek professional servicing immediately to prevent further damage.

Pros and Cons

Pros

  • Exceptional low-light visibility with Lumibrite Pro
  • Reliable and accurate in-house automatic movement (Calibre 6R35)
  • Robust 200m water resistance suitable for professional diving
  • Durable construction with sapphire crystal and stainless steel
  • Comfortable silicone strap for extended wear
  • Unique 'turtle' design appreciated by watch enthusiasts

Cons

  • The 'turtle' case shape might not suit all aesthetic preferences

Setup, Compatibility & Care

Setup: This is an automatic watch, meaning it is powered by the movement of the wearer's wrist. To start the watch, gently shake it for about 30 seconds. If you need to set the time or date, pull the crown out to the first or second position (depending on the movement's specific function) and adjust accordingly. Ensure the crown is pushed back in or screwed down after setting to maintain water resistance.

Compatibility: The watch is designed to be worn by anyone appreciating dive watch aesthetics and functionality. The silicone strap is compatible with standard lug widths, allowing for aftermarket strap changes if desired, though the original strap is optimized for diving comfort and durability.

Care:

  • After Diving: Always rinse the watch with fresh water after exposure to salt water or chlorine to prevent corrosion and residue buildup.
  • Cleaning: Clean the case and strap with a soft, damp cloth. Avoid harsh chemicals or abrasive materials that could damage the finish or lume.
  • Water Resistance: Ensure the crown is always screwed down or pushed fully in before exposure to water. The water resistance rating is valid under normal conditions; consult a professional for periodic testing, especially if the watch is frequently used for diving.
  • Storage: Store the watch in a cool, dry place when not in use. If storing for an extended period, consider a watch winder to keep the automatic movement running.
