Strap for Big Crown ProPilot Altimeter Meter / Green Textile

The lug width of this model is precisely 23 millimetres. This is a non-standard dimension that requires custom-made straps or those specifically constructed for this family. Accurate measurement is performed using a digital calliper, positioned perpendicular to the lug shoulder, measuring the net distance between the inner walls of the lugs.

For the ProPilot we primarily recommend Mississippi alligator with pronounced grain, which provides sober elegance whilst maintaining the structural solidity necessary to support a 47-millimetre case. Vegetable-tanned calf represents the sophisticated alternative with natural patina development. For operational contexts, butyl rubber and NATO straps ensure versatility and moisture resistance.

Removing the strap requires a spring bar tool. Position the watch on a soft surface, insert the tool tip into the lug access hole, gently push the spring pin downward to release pressure, then extract the pin. Repeat the operation on the opposite lug. To install the new strap, align the lug channels with the access holes and insert the spring pin until fully locked.

Yes, provided it is manufactured to the 23-millimetre lug width specification. It is essential that the strap's construction quality is consistent with the instrument's value and the mechanical resistance required by a 47-millimetre case. Milano Straps straps are custom-made with premium materials and guarantee precise compatibility and durability over time.

A quality leather strap, subject to ordinary wear, maintains structural integrity for 3-5 years. Durability varies according to frequency of wear, climatic conditions, type of tanning and maintenance. Vegetable-tanned leathers develop natural patina that enhances aesthetics over time. Milano Straps offers restoration and replacement services to extend the strap's useful life.
