Luminox Leatherback SEA Turtle 100M

The Luminox Leatherback SEA Turtle XS.0301.BO.L is a Swiss-made sports watch built for daily wear and water-based activity. Its Carbonox case measures 39.00 mm and carries a 100-metre water-resistance rating. A black analog dial with Arabic markers pairs with a silicone strap and buckle clasp. The quartz movement provides battery-powered timekeeping with a date display.

Suits active users wanting a lightweight

This model fits wearers who value low-light readability from Luminox light technology and a comfortable silicone band for sport use. The 100-metre rating supports swimming and recreational diving. Buyers who require a mechanical movement, a metal bracelet, or a larger case diameter should consider other options. The mineral crystal and buckle clasp are fixed specifications.

100-metre water resistance defines the use case

The 100-metre rating is the single figure that determines whether this watch matches the intended activity. It covers surface swimming, snorkelling and shallow recreational diving. It does not satisfy the requirements for deep saturation diving or professional mixed-gas work. Verify that the rating aligns with the depth profile you plan to encounter.

Questions about this item

Will the 39.00 mm case fit under a standard shirt cuff?

The 39.00 mm diameter sits flat on the wrist, so most shirt cuffs close over it without catching.

How do I set the date on the quartz movement without damaging it?

Pull the crown to the first position, turn until the date flips, then push the crown back in; avoid changing the date between 9 PM and 3 AM.

How often should the silicone strap be replaced for a secure fit?

Inspect the silicone band yearly; replace it if you see cracks, stretching or hardening so the buckle clasp stays secure.
