Leatherback SEA Turtle Series
This watch is inspired by one of the ocean’s toughest sea creatures that travels thousands of miles across the Atlantic and Pacific Ocean, the Leatherback SeaTurtle . Just like its namesake this timepiece is tough and durable featuring a 44mm CARBONOX™ case and uni-directional bezel. The sand tone markers and hands create a stunning contrast to the black dial, watch case and bezel. The classic case design with the protected crown balanced by an opposite outcropping has created the iconic “turtle shape”. The watch is powered by a Swiss Quartz movement and equipped with a SuperLumi-Nova bezel light at 12 o'clock, eight LLTs, and a black waterproof rubber strap ensuring readability and comfort in low light conditions on land or in water up to 100 meters.

Measure your ring size at home in minutes with our printable ring sizer and conversion chart.
How to measure your ring size
A good fit is snug enough to stay put, loose enough to slide over your knuckle. Print our ring sizer on A4 paper at 100% scale (no "fit to page") and check the 5cm line with a ruler, then choose a method below.
Download printable ring sizerUse a ring you already own
Easiest if you have a ring that fits the finger you're shopping for.
- Place your ring over the printed circles, starting with the smallest.
- Stop when the circle's outline sits just inside the ring's inner edge.
- That circle is your size.
Use the ring sizer strip
No ring to measure? The paper strip works just as well.
- Cut out the strip along the dashed line, then cut the slit.
- Wrap it around the base of your finger, printed side out.
- Feed the narrow end through the slit until it feels snug.
- Read the size where the strip meets the slit.
Between sizes? Choose the larger size.
Best time to measure: at the end of the day, when fingers are warm. Cold fingers read smaller.
Wide band? Bands 6mm and wider fit tighter, so consider going up half a size.
