Why choose FKM rubber

The Fifty Fathoms is a dive watch, and FKM fluoro rubber holds up to salt water, chlorine and sunscreen better than standard silicone. It stays firm instead of stretching and does not pick up lint or turn sticky over the years. FKM is slightly stiffer than silicone in the first days and softens with wear.

Why 23mm matters

A 23mm lug width is uncommon. A 22mm strap leaves a visible gap and can shift on the spring bars, and a 24mm strap will not fit. This strap is cut to 23mm for a flush, secure fit.

How to fit it

1. Lay the watch face down on a soft cloth so the case and crystal are protected.
2. Use a spring bar tool to compress the spring bar at each lug and remove the current strap.
3. Seat a spring bar in each end of the new strap, place one tip in the lug hole, compress the other tip and let it click into place.
4. Pull gently on both sides to check it is locked in. Never open the case back: the strap attaches only at the lugs.
