The Ocean Star M026.430.36.091.00, seen from the bench

The Mido Ocean Star M026.430.36.091.00 is a 42.5mm stainless steel dive watch launched in 1959, embodying Swiss watchmaking tradition with robust technical construction and uncompromised readability. It features the ETA caliber C07.621 movement with hours, minutes, seconds, date, and day functions. The AISI 316L stainless steel case with satin and polished finishing offers superior corrosion resistance, while the anti-reflective sapphire crystal, unidirectional bezel, and screw-down crown ensure water resistance to ISO 6425 standards. The 22mm lug width maintains precise proportions between case diameter and wrist wear, preventing excessive lateral play during diving operations.

Frequently asked questions

What is the lug width of the Mido Ocean Star M026.430.36.091.00?

The lug width (misura ansa) of the Mido Ocean Star M026.430.36.091.00 is 22mm. This measurement is critical when purchasing a compatible strap: a different lug width will not fit correctly into the watch lugs. To verify, measure the distance between the inner lugs with a digital calliper, without applying force.

Which strap do you recommend for the Mido Ocean Star M026.430.36.091.00?

For a diving watch of this calibre, we recommend vegetable-tanned Tuscan leather in tobacco brown or natural cognac if you value patina development and timeless aesthetics. If maritime use is frequent, FKM vulcanised rubber offers superior chemical durability and grip when wet. NATO nylon is the versatile choice for those who change straps frequently.

How do I change the strap on my Mido Ocean Star M026.430.36.091.00?

Position the watch on a soft cloth with the strap interior facing you. Locate the spring bars (perni) inside the lugs. Using a strap removal tool or a small lever, press the pin toward the watch centre, lifting one end of the bar slightly. Once the pin partially retracts, remove the old strap. Align the new strap holes with the lugs and reinstate the spring bar by pressing until it seats fully.

Is an aftermarket strap in 22mm compatible with the Mido Ocean Star M026.430.36.091.00?

Yes, any artisanal strap with 22mm-dimensioned holes is compatible with the Mido Ocean Star M026.430.36.091.00, provided the holes are centred and edges are smooth. Before purchase, confirm the supplier explicitly states '22mm', as a 0.5mm variation can cause friction or excessive play on the stainless steel lugs.

How long does a Tuscan leather strap last on my Mido Ocean Star M026.430.36.091.00?

A vegetable-tanned Tuscan leather strap, with proper maintenance, has an average lifespan of 4–6 years with daily wear. Durability depends on exposure to humidity, direct sunlight and how frequently you wear the watch. If not submerged completely, gentle drying after water contact and light conditioning with natural oil every 12 months will significantly extend the strap's life.
