Frequently asked questions

What is the lug width of the Omega Seamaster Diver 300M 212.32.41.20.04.001?

The lug width of the 212.32.41.20.04.001 model is 20 millimetres. This measurement is the space between the two lugs of the case and determines the width of the strap you can fit. Any strap with a 20mm lug width will be perfectly compatible with this Seamaster.

Which strap do you recommend for the Seamaster Diver 300M Commander?

For the Commander 212.32.41.20.04.001 we recommend alligator straps (dark brown or black for formal elegance), black or navy blue calf leather for everyday versatility, or black rubber to emphasize the diving nature. Alligator creates the best aesthetic contrast with the matte black dial and satin-brushed steel case.

How do you change the strap on the Seamaster Diver 300M 41mm?

To change the strap, use a dedicated tool to extract the pins from the lugs. Position the watch on a soft cloth to avoid scratches, locate the small holes on the lugs where the pins reside, and gently push inward to slide them out. Insert the new strap by aligning the lugs to the holes and reinsert the pins until they are fully seated.

Is a third-party strap compatible with the 212.32.41.20.04.001?

Yes, any aftermarket strap with a 20mm lug width is completely compatible. Our handcrafted straps are specifically made for this measurement and guarantee a precise and secure fit with your Seamaster Commander case.

How long does a leather strap last on this watch?

A premium leather strap such as alligator or calf, with ordinary care (avoiding prolonged exposure to unrinsed salt water, direct sunlight and extreme humidity), maintains excellent appearance and functionality for 3-5 years. With regular maintenance and periodic treatments with specific creams, the lifespan extends further. Casati Milano straps include an 18-month warranty and can be regenerated or replaced with new personalised models.
