Strap for Speedmaster Professional Missions Apollo 16

The lug width of the Speedmaster Moonwatch 3597.19.00 is 20 millimetres. This measurement is specific and non-negotiable: it corresponds to the internal distance between the two spring bars of the case. Always ensure that the strap is explicitly declared for 20 mm, as even small variations (19 mm or 21 mm) prevent correct installation.

There is no single choice, but it depends on use and aesthetic preference. Black alligator offers sporty elegance with chromatic contrast against the brushed steel case; vegetable-tanned calf creates an informal look and develops natural patina over time; shell cordovan is the most sophisticated choice for those seeking discreet luxury; rubber is ideal if the Moonwatch becomes an everyday instrument watch. NATO canvas remains a versatile casual option.

The strap is changed using a spring bar tool (specialized tool) to press the spring bars and remove the previous strap. Position the tool inside the case, gently pushing the bar inward until it releases. Once the old strap is removed, insert the spring bars of the new strap into the case lugs and release the bar. The process requires care to avoid scratching the case. If you lack experience, entrust the work to a professional.

Yes, absolutely. Quality aftermarket straps are fully compatible with the Moonwatch, provided they have the correct lug width (20 mm) and spring bars of the same width. Brands specializing in artisanal straps often offer superior quality to the original Omega strap, with greater customization options (leather, colour, length, stitching) and more accessible prices.

Durability depends on the material and use. A quality artisanal alligator or calf strap, with vegetable tanning, typically lasts 3–7 years under moderate daily use conditions. Vegetable-tanned leather visibly ages (develops patina, changes tone) but maintains structural integrity. Factors such as exposure to sweat, humidity and sunlight accelerate wear. An 18-month warranty is the standard for premium artisanal straps, guaranteeing coverage for manufacturing defects and premature wear.
