Prefer to do it yourself? Add our watch pin tool to your order. Once you have the tool, future swaps take 30 seconds.
The Duro community does this all the time. It is one of the most swap-friendly dive watches out there.
The tool
Add the watch pin tool. Skip the watchmaker.
Most analogue watches use spring bars to hold the strap. This precision pin tool releases them in seconds: forked end pops the spring bar out, pin end pushes it back in. No scratches, no jeweller, no waiting. Future strap swaps take seconds at home.
Stainless steel tips. Knurled grip. Spare pins in the cap.

A photo went viral showing Bill Gates wearing a Casio MDV-106 at a charity gala — a $30 dive watch on the wrist of one of the richest people alive. The watch community loved it because it reinforced something collectors have known for years: the MDV-106 punches way above its price. It has been a cult favourite ever since.
You need a spring bar tool to swap the band. Any watch repair shop will do it in about 2 minutes, usually for free. If you want to do it yourself, add our watch pin tool. The Casio Duro is one of the most band-swap-friendly watches around, the lugs are well-drilled and accessible.
Yes. Our premium silicone is non-absorbent, dries quickly, and holds up well in water. It is not rated for deep diving but handles beach, pool, and daily water contact without any issues. The woven texture also resists odours better than rubber. Many Duro owners who use their watch at the beach find silicone more comfortable than rubber in hot weather.
14-day returns from delivery, no questions asked on unworn items. If the size is wrong, we will exchange it. Contact us via the website or email and we will sort it within 24 hours.
