Strap for Big Pilot 43 Top Gun Woodland

The lug width of the Big Pilot IW3298-02 is 21 millimetres. This measurement is the distance between the case lugs and is standard for all straps compatible with this model. To verify it, place a ruler between the case lugs: the measurement in millimetres is your lug width.

The best strap depends on your intended use: alligator leather in vegetable tanning offers formal aesthetics and develops patina over time; rubber is ideal for sports-oriented contexts thanks to grip and moisture resistance; smooth calfskin guarantees maximum elegance but requires regular maintenance. Burgundy or black shell cordovan represents a balanced approach between tradition and durability.

To change the strap, obtain a spring bar tool or contact a specialist watchmaker. Position the watch on a soft cloth, locate the case lugs, insert the tool to compress the internal spring, and extract the pin. Repeat on the other side. Reverse the operation to install the new strap. Atelier Casati Milano provides this service by appointment.

No, the 21-millimetre lug width is specific to large-cased models. 20-millimetre or 22-millimetre straps will not fit correctly. It is essential to verify compatibility before purchase. All 21mm straps from Milano Straps are guaranteed compatible with the Big Pilot IW3298-02.

Durability varies depending on the material and maintenance: vegetable-tanned leather (alligator, calfskin) lasts 3-5 years with daily wear; shell cordovan can last 5-7 years thanks to its density and natural oils. Regular maintenance—cleaning and conditioning—significantly extends service life. Milano Straps artisanal straps include an 18-month guarantee against manufacturing defects.
