Frequently asked questions

What is the lug width of the Omega Speedmaster Moonwatch 3097.30.00?

The lug width is 20mm. By measuring the internal distance between the two lateral lugs of the case, you will have exactly 20mm. This parameter is critical to ensure proper strap attachment and watch security during use.

What is the best strap for the Omega Speedmaster Moonwatch platinum?

For the Moonwatch in platinum, black alligator is the most coherent choice with the original minimalist style. Shell cordovan with developed patina offers a richer alternative; for those preferring absolute sobriety, vegetable-tanned calf with natural aging. Ballistic NATO remains ideal for intensive sports use.

How do I change the strap on my Omega Speedmaster 3097.30.00?

The strap is attached via two pins (lug pins) that pass laterally through the case lugs. For the change you need a specific tool: remove the first pin with a dedicated tool (lug pin removal tool), separate the old strap, position the new one aligned with the lugs and reinsert the pin with gentle pressure until you feel the locking click. If you are not experienced, consulting a certified watchmaker is recommended.

Are aftermarket straps really compatible with the Moonwatch 3097.30.00?

Yes, as long as the lug width is exactly 20mm. Any artisanal strap with certified 20mm lug width fits correctly. At milanostraps.it you will find compatible straps in various leathers: always verify that the measurements are declared for 20mm to avoid surprises.

How long does a leather strap last on the Moonwatch with daily use?

The durability depends on the material and intensity of use. Alligator resists 3-4 years of intensive daily use before showing signs of stress. Shell cordovan is more robust, up to 5-6 years. Vegetable-tanned calf, softer, requires replacement every 2-3 years in a high-stress environment. NATO straps last over 5 years if properly maintained. Casati Milano warranty is 18 months.
