Frequently asked questions

What is the lug width of the Omega Seamaster Planet Ocean 232.32.42.21.01.001?

The lug width of the Seamaster Planet Ocean 232.32.42.21.01.001 is 20mm. This width is the standard construction measurement for the 42mm case and must be measured precisely between the two contact points of the case to ensure correct compatibility with aftermarket straps.

Which strap is best suited for the Seamaster Planet Ocean 42mm in steel?

For this brushed stainless steel case, vegetable-tanned alligator leather offers maximum aesthetic sophistication and allows the leather to develop a patina over time. Nappa calf represents a more versatile daily alternative, while shell cordovan guarantees exceptional durability. For marine use, opt for NATO or FKM rubber to preserve water resistance.

How do you change the strap on an Omega watch with 20mm lug width?

The procedure requires a spring bar tool to extract the pins that secure the strap to the case lugs. Position the tool's end vertically under the lug, compressing the spring bar laterally until the strap disengages. Repeat on the other side, then insert the new strap by aligning the holes and snapping the spring bar into position. The operation requires care to avoid scratching the case.

Are there aftermarket straps compatible with the Seamaster Planet Ocean 232.32.42.21.01.001?

Yes. Any strap designated for 20mm lug width is compatible with this case. MilanoStraps offers a specialized collection of 20mm straps in fine leather (alligator, calf, shell cordovan) and technical materials, all customizable in size, initials and stitching thread choice, with fast shipping.

How long does a leather strap last on a daily-wear wrist watch?

Durability depends on tanning and usage. Vegetable-tanned leather, such as quality alligator and shell cordovan, resists 2 to 4 years with daily use not subjected to impacts or extreme humidity. A nappa calf strap tends to last 18-30 months. Exposure to sweat, water and heat accelerates wear. MilanoStraps guarantees 18 months on bespoke straps and offers restoration services.
