The Heritage

The Ocean Star M026.830.38.041.00 is a 40.50mm stainless steel 316L diving watch launched in the 1950s, featuring a unidirectional rotating bezel, integrated lugs, and a brushed dial. It houses the ETA C07.621 caliber movement with a 42-hour power reserve and COSC certification, displaying hours, minutes, seconds, date, and day with water resistance to 30 bar. The sapphire crystal and nickel-plated case represent mid-to-high quality standards. The 21mm lug width is precisely specified for this model to ensure ergonomic strap compatibility without adjustment.

FAQ

What is the lug width of the Mido Ocean Star M026.830.38.041.00?

The lug width is 21mm. This measurement corresponds to the distance between the inner edges of the case lugs on the Mido Ocean Star M026.830.38.041.00. To verify it correctly, use a digital calliper positioned perpendicular to the case's lateral mounting points.

Which strap do you recommend for the Ocean Star M026.830.38.041.00?

It depends on intended use: for formal elegance, we recommend shell cordovan or vegetable-tanned calf leather; for sport and water resistance, a NATO strap or FKM rubber. All must feature a 21mm lug width. Ideal colour choices are cognac brown, black, or navy blue depending on context.

How do I change the strap on my Mido Ocean Star?

The strap is mounted via the case lugs. Use a dedicated spring bar tool to compress the internal spring of each lug, remove the old strap and insert the new one. Ensure the strap ends are fully seated in the lugs and the spring returns to its correct position.

Can I use an aftermarket 21mm strap on this watch?

Yes, any strap with a 21mm lug width is compatible with the Ocean Star M026.830.38.041.00. Artisanal leather, NATO or FKM rubber straps specifically cut for 21mm will mount without issue and offer equivalent build quality to the case.

How long does a leather strap last on this model?

A quality leather strap (shell cordovan or vegetable-tanned calf) typically lasts 4–6 years with regular daily wear, extending to 8–10 years with intermittent use. Longevity depends on sun exposure, water contact, perspiration and maintenance. Periodic cleaning with a damp cloth extends strap lifespan.
