FAQ

What is the lug width of the Omega Speedmaster Moonwatch DD 145.0022?

The lug width is exactly 20mm. This measurement is essential for choosing a compatible strap: it must be measured between the two lugs protruding from the case. A 19mm strap would be loose, while a 21mm strap would be impossible to fit. Always verify this dimension before purchasing.

What strap material is recommended for the Moonwatch?

For the DD 145.0022 we recommend vegetable-tanned alligator (premium, patina evolves over time), English calf Derby (everyday, silky touch), or shell cordovan (noble, natural lustre). The choice depends on use: formal versus sporty. Avoid chemically-treated leathers; vegetable tanning ennobles the strap with age.

How do I change the strap on my Speedmaster Moonwatch?

Use a spring bar tool to compress the spring bars of the internal lugs. Keep the old strap horizontal, insert the tool tip into the discharge holes, compress and slide outward. Proceed carefully to avoid scratching the case. If you are uncertain, entrust the operation to an expert to protect your watch.

Can I use an aftermarket strap on my Speedmaster Moonwatch?

Yes, provided the strap has a lug width of 20mm and compatible internal lugs. Milano Straps produces handcrafted straps specifically sized for the Moonwatch DD 145.0022, in alligator, calf and rubber, ensuring perfect fit without additional adapters. Italian construction quality ensures durability equal to the original movement.

How long does a leather strap last on an Omega Speedmaster?

A handcrafted vegetable-tanned strap typically lasts 4-5 years with daily use, developing an elegant patina over time. Lifespan varies based on climate, humidity and frequency of use. Denser leathers (shell cordovan, alligator) resist longer. Milano Straps offers an 18-month warranty on all custom straps, with maintenance and restoration options available.
