Strap for Seamaster Planet Ocean 600M Co-Axial 37.5 Chronograph Stainless Steel / Orange / Rubber

The Omega Seamaster Planet Ocean 37.5mm has a lug width of 20 millimetres. This measurement represents the distance between the inner edges of the case lugs where the strap lugs are housed. You can verify this yourself with a digital caliper or by contacting Omega service with the reference number 222.32.38.50.01.003.

It depends on the context of use. Vegetable-tanned alligator offers maximum aesthetic sophistication and a patina that ages elegantly. Shell cordovan is ideal for those who want extremely durable leather that can be polished over time. Fine-grained calf represents the compromise between elegance and everyday durability. FKM rubber is the technical choice for frequent contact with salt water or humid environments.

The strap is replaced by removing the metal spring bars (also called strap lugs) from the case lugs. Generally, a thin spring bar tool is required to lift the spring bar and free it from the hole. Insert the new strap ensuring that the lug width is exactly 20mm, then reinsert the spring bars. Some prefer to entrust this task to a trusted watchmaker to avoid scratches on the case.

Yes, provided the lug width is exactly 20 millimetres. On milanostraps.it you will find a collection dedicated to 20mm straps, made with the same bespoke quality construction standards. The important thing is to verify that there are no lug width tolerances: even half a millimetre difference can cause visual misalignment or mounting difficulties.

A strap with vegetable tanning typically lasts 3-5 years with daily use, depending on exposure to moisture, perspiration and temperature fluctuations. Alligator tends to be more resistant (5-7 years), while shell cordovan can exceed 7-10 years. Straps made by Casati Milano include an 18-month warranty. To extend the lifespan, it is advisable to dry the strap after water exposure and store it in controlled humidity conditions.
