Pilot Strap for the IWC Big Pilot 43: Brown Crocodile
The IWC Big Pilot 43 brings the Big Pilot's instrument-panel presence down to a 43mm case, and that presence is exactly what makes strap shopping tricky: thin dress straps disappear under it, and ready-made pilot straps rarely come in exotic leathers. This order, shipped to Victoria, Australia, solves both problems at once — a brown crocodile strap cut in our pilot style, built to the owner's measurements and sized for a buckle they already own.

Why these choices
The pilot cut is what makes this build work on this watch. It keeps the strap purposeful — a flatter, tool-watch profile rather than a rounded dress taper — while full padding gives it enough shoulder to sit level with a 43mm case. The V-square tip keeps the tail clean through the keepers instead of rounding off into dress-strap territory.
Crocodile handles the refinement. It is the same hide family as alligator, softens with wear, and takes on a hand-rubbed patina over time, so the strap builds character alongside the watch rather than simply aging. Side stitching in matching thread was the right restraint here: it reinforces the edges while leaving the scale pattern, not the thread, as the visual event. There are more builds like it in our crocodile leather watch straps collection, and the wider brown leather straps range covers the color across other hides.
The 18mm buckle width is cut for hardware the owner already has. Like every use-my-own-buckle order, the strap ships without a buckle so the original pin buckle or deployant carries straight over — no spare parts drawer required. Length stayed at our standard 75/125mm, made to the measurements on the order rather than pulled from a rack.

FAQ
What is the best pilot strap for an IWC Big Pilot 43?
One made to the watch rather than adapted to it. A pilot strap for an IWC Big Pilot 43 needs enough padding to carry the case, and because every VGreen strap is built to order, the leather, length, stitching, and tip shape are all chosen per build — this one started from our brown crocodile watch strap configurator.
Can I use my own IWC buckle on a custom strap?
Yes. Choose the use-my-own-buckle option and give us your buckle width — this order was built at 18mm — and the strap arrives without a buckle, ready to take your hardware.
Every strap is made to order; allow two to three weeks to delivery. Start from the custom leather watch straps collection and build yours around your watch.
