The Luminox FORCE BLUE Official Watch is purpose-built for those who answer the call above and below the surface of our oceans. Developed in collaboration with FORCE BLUE, the world’s only nonprofit organisation deploying former Special Operations veterans on marine conservation missions, this Swiss Made dive watch combines mission-ready performance with a meaningful purpose. A robust 316L stainless steel case, lightweight CARBONOX™ unidirectional bezel, screw-in crown and case back for water resistance up to 200 metres, and an expandable rubber strap with integrated wetsuit extension make it ready for demanding underwater operations.
Blue and yellow Luminox Light Technology ensures constant visibility in any light condition for up to 25 years, while the dial showcases FORCE BLUE’s signature rope motif rendered in Super-LumiNova® alongside gold accents inspired by the organisation’s emblem. Once charged by light, the rope motif glows in the dark, revealing a distinctive design inspired by FORCE BLUE’s mission beneath the surface. Built to perform. Inspired to protect.

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.
