Why choose FKM rubber

FKM is a dense fluoroelastomer rubber with strong resistance to heat, chemicals and wear. It is water resistant and lightweight, so it suits days outdoors, sport and summer wear on a pilot or dress watch that would otherwise sit on leather. Cyan and red add colour, while black, blue and brown stay understated. If you own a Portugieser 390502, 390503 or 390211 and want curved ends that meet the case, compare our curved-end rubber strap for IWC Portugieser.

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.
