Strap for Speedmaster Professional Missions Gemini VII

The lug width of the Omega Speedmaster Moonwatch 3597.05.00 is 20 millimetres. This measurement is the distance between the two lugs of the case and determines compatibility with straps. A strap of different width (18mm, 22mm) will not fit into the lugs. Always verify this specification before purchase to avoid incompatibility.

The Moonwatch 3597.05.00 pairs with various materials depending on your style. Alligator offers luxury and evolving patina over time; vegetable-tanned calf provides softness and natural aging with rich nuances; NATO ballistic nylon emphasises military and aeronautical heritage; vulcanised rubber represents the most sporty and resistant choice. The choice depends on use and personal aesthetic preference.

To change the strap on the Moonwatch, you need to remove the lug pins using a specific tool called a spring bar tool or spring bar remover. Insert the flat end of the tool into the slot underneath the lug, compress the internal spring and extract the pin. Once the lugs are free, align the new strap and reinsert the pin. It is advisable to entrust this task to an expert watchmaker to avoid damage to the case.

A quality leather strap, made with vegetable tanning or alligator, has an average lifespan of between 3 and 5 years under daily wear conditions. Longevity depends on water exposure, cleaning frequency, the leather itself and usage habits. By avoiding prolonged immersion and cleaning regularly, the strap acquires a natural patina as it ages elegantly.

Yes, any strap with a 20mm lug width is compatible with the Moonwatch 3597.05.00. Many quality artisanal aftermarket straps offer a valid alternative to original Omega straps, often with greater customisation in material, colour and finishes.
