Strap for Speedmaster Professional Moonwatch Apollo - Soyuz 25th Anniversary

The reference 3195.59.00 features a 20 millimeter lug width. This measurement is standard across all modern Speedmaster Moonwatch models and is the size that allows comfortable passage even through the buttonholes of a formal dress shirt or tuxedo jacket.

For a yellow gold Moonwatch, medium brown alligator or cognac shell cordovan offer the best balance between aesthetics, elegance, and durability. Both leathers age magnificently and create a natural color resonance with the yellow metal. For less formal daily wear, vegetable-tanned calf is an excellent and versatile choice.

The Moonwatch uses a simple lever spring bar to anchor the strap to the case. Using a dedicated tool or thin blade, press the spring bar toward the center of the case to extract it from one side, slide off the old strap, and reinsert the spring bar into the new strap. The operation requires care to avoid scratching the gold case.

Yes, provided it conforms to the 20 millimeter lug width and is made from noble materials. High-quality artisanal straps in alligator, shell cordovan, or calf adapt perfectly and transform the wearing experience of the watch. We recommend choosing suppliers that guarantee technical compatibility and offer warranties on craftsmanship.

A quality leather strap — alligator, cordovan, or calf — typically lasts 3–5 years with regular wear (3–4 times per week). Longevity depends on environmental humidity, frequency of use, and care: treating the leather with specific creams and storing the watch in a dry location significantly extends its life. Artisanal straps age magnificently and can be restored through maintenance interventions.
