Aftermarket Rubber Band for IWC Portofino, Top Gun, Big Pilot – 22mm

Three IWC references that rarely appear on the same listing — and for good reason. The Portofino’s dress-watch refinement, the Top Gun’s matte ceramic aggression, and the Big Pilot’s oversized aviation brief seem to occupy completely different corners of the catalogue. What they share, at 22mm, is the lug width that makes this band the right fit for all three. The IWC Portofino / Top Gun / Big Pilot Rubber Band covers that common ground: rubber, 22mm, 125mm + 75mm, with a folding or pin buckle at 18mm. The configuration that works when leather or canvas isn’t what the day calls for.

One Rubber Band. Three Different Watches. One Correct Lug Width.

• Rubber construction — the material that handles what leather and canvas can’t — rubber doesn’t need conditioning, doesn’t absorb moisture, and doesn’t degrade from the water exposure that would age a leather or canvas band in months. It performs identically coming out of a pool, a sea swim, or a summer downpour as it does on a dry weekday wrist — which makes it the practical default for any of these three watches in an active environment, however different their characters might otherwise be.
• 22mm — the shared lug width across three distinct references — the Portofino, Top Gun, and Big Pilot share a 22mm lug specification across their ranges, making a single correctly sized rubber band a genuine multi-watch solution. Each reference sits differently on the wrist and wears a different character, but the band seats flush at each case identically at 22mm.
• 125mm + 75mm length — proportioned to suit the 22mm lug width across the range of wrist sizes these three references typically attract. The 125mm long side accommodates most wrist circumferences without running short, while the 75mm short section positions the buckle correctly and seats the tail cleanly through the keeper.
• Folding buckle or pin buckle at 18mm — configured for the reference — on the Portofino, the pin buckle is the correct choice: slim, understated, consistent with a dress watch’s visual language even on rubber. On the Top Gun and Big Pilot, the folding buckle suits an active, performance-oriented wear context better — more secure, one-handed to operate, and flat against the wrist under movement. Both options available at 18mm for exactly this reason.

For the Three Watches That Share a Lug Width and Nothing Else.

The appeal of a rubber band for these three references comes from different places. On the Portofino, it’s the warm-weather or weekend alternative to leather — the configuration that lets a dress watch leave the office without pretending it belongs there. On the Top Gun, rubber is the native material — the choice that matches the watch’s own tactical, no-nonsense brief. On the Big Pilot, it’s the active daily option that preserves a premium leather strap for the occasions that call for it.

This band is the right choice for:

• Portofino owners who want a warm-weather or casual alternative to leather that keeps the watch wearable through summer heat and occasional water contact without replacing the leather strap they already own.
• Top Gun owners for whom rubber is the instinctive and historically correct material choice — tactical, performance-ready, and entirely in keeping with the watch’s design brief.
• Big Pilot owners rotating between leather for formal and business wear and rubber for active and outdoor contexts, extending the leather strap’s life while keeping the watch on the wrist daily.
• Multi-IWC collectors who own more than one of these references and want a single correctly sized rubber band that moves between them without a separate purchase for each.
