Frequently asked questions

What is the exact lug width of the Omega Seamaster 165024?

The lug width of the Seamaster 165024 is 20 millimetres. This measurement represents the internal space between the two lugs of the case and is the fundamental technical specification for selecting a compatible replacement strap. Aftermarket straps must respect this dimension precisely to ensure a perfect fit without play or forcing.

Which strap is most suitable for the Seamaster 165024?

For the Seamaster 165024, the ideal strap depends on intended use and dial colour. A cognac or dark brown alligator is the most versatile and elegant solution for those seeking a dress-sport approach. If you prefer a patina that improves over time, calf leather with vegetable tanning is excellent. For sporting or diving use, a vulcanised rubber strap guarantees complete water resistance and comfort in humid environments.

How do you change the strap on a Seamaster 165024?

Strap replacement is accomplished using a spring bar removal tool. Position the case securely and gently press the spring bar ferrule with the tool until the lug is freed. Once the spring bar is removed, the old strap slides out easily. The new strap is inserted by aligning the holes with the lugs, then the spring bar is reinserted until it clicks into place.

Can I use an aftermarket strap on my Seamaster 165024?

Yes, absolutely. Aftermarket 20-millimetre straps are perfectly compatible with the Seamaster 165024, provided they respect the correct lug width. Choosing straps crafted by specialist artisans ensures construction quality, precise finishing and noble materials that enhance the aesthetic qualities of your vintage watch.

How long does a leather strap last on a Seamaster 165024?

The lifespan of a leather strap depends on material quality, intensity of use and maintenance. A high-quality alligator or shell cordovan strap typically lasts 5-10 years with regular wear. Vegetable-tanned calf tends to last 3-7 years, developing a fascinating patina over time. To extend strap life, avoid prolonged moisture exposure and occasionally apply protective waxes specifically formulated for leather.
