Strap for Speedmaster Professional Missions Apollo 7

The lug width is exactly 20 millimetres. This measurement corresponds to the internal distance between the case lugs. It is the standard for this generation of Speedmaster and determines compatibility with any aftermarket strap. To measure accurately, remove the spring bar and measure perpendicularly with a digital calliper between the inner edges of the lugs.

It depends on usage. For formal wear: natural alligator with satin steel buckle. For sports: FKM rubber strap or NATO in ballistic nylon. For everyday casual: European calf leather with progressive patina. The stainless steel Speedmaster accepts any leather material thanks to its neutral aesthetic vocabulary.

The spring bar is accessible from the inner side of the case. Position the watch on a soft cloth to avoid scratches. Use a fine-tip screwdriver to remove the spring bar (counterclockwise rotation or outward pressure depending on the type). Once the spring bar is removed, the strap will come off. Insert the new strap by aligning it with the lugs and reinsert the spring bar. Verify that it does not rotate freely: it must be securely anchored.

Yes, provided the lug width is exactly 20mm. Any strap with a 20mm lug width will fit perfectly. On milanostraps.it you will find a selection of 20mm straps in various leathers: alligator, calf, shell cordovan and rubber, all handcrafted in Italy and shipped promptly.

With moderate use (worn 5-6 days weekly), a high-quality artisanal leather strap lasts 3-5 years. If made in alligator or shell cordovan, longevity reaches 6-7 years. The main wear occurs at the keeper (friction tears) and buckle (plating wear). Minimal maintenance (cleaning with a damp cloth and annual oiling) significantly extends the strap's useful life.
