Why choose a pilot-style leather strap

The 135+55mm split places the buckle to the side of the wrist, as on a traditional pilot strap, so the long end wraps neatly and the case sits centred. Leather is the dressier choice for the office and evenings. For a casual, military-inspired look, try the canvas strap for IWC; for summer, sport and water, the FKM rubber strap for IWC.

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.

Frequently asked questions

Why is the short side only 55mm?

That is the pilot-style split: a short buckle side and a long tail side, which puts the buckle off to the side of the wrist.

Which lug widths are available?

20mm, 21mm and 22mm.

Can I get a folding buckle?

Yes. Choose a pin or folding buckle in silver, gold or rose gold.
