Frequently asked questions

What is the lug width of the Mido Ocean Star M026.629.37.291.00?

The lug width of the Mido Ocean Star M026.629.37.291.00 is 22mm. This dimension corresponds to the distance between the two spring bars (the pins that anchor the strap). A compatible strap must have an opening of exactly 22mm to fit the case correctly. Measuring this dimension with a digital calliper perpendicular to the lugs is essential before purchasing an aftermarket strap.

Which strap is recommended for the Mido Ocean Star M026.629.37.291.00?

The ideal strap for this model depends on its intended use. For aesthetic upgrade: an alligator with vegetable tanning in dark brown or black, creating a noble contrast with the ceramic and steel case. For sport-classic aesthetic: a Tuscan calf tinted in brown, grey, or black that develops elegant patina over time. For a pure tool watch interpretation: a Cordura NATO or FKM rubber strap that emphasises the model's diving heritage.

How do you change the strap on the Mido Ocean Star M026.629.37.291.00?

Strap replacement is straightforward: place the watch on a soft surface. Locate the two spring bars (metal pins) that pass through the lugs. Use a dedicated tool or small flathead screwdriver to push the spring downward, releasing one end of the strap. Repeat on the other side. Insert the new 22mm strap into the spring bars, ensuring the spring clips back into position. Verify the strap is securely fastened before wearing the watch.

Which aftermarket straps are compatible with the Mido Ocean Star M026.629.37.291.00?

The Mido Ocean Star M026.629.37.291.00 is compatible with any 22mm aftermarket strap: alligator leather, calf skin, suede, shell cordovan, woven NATO, FKM rubber or vulcanised silicone straps, Cordura fabric straps. Choice depends on intended use (professional, diving, casual) and aesthetic preference. Milano Straps offers a curated selection of artisanal vegetable-tanned leather straps specifically compatible with this lug width.

How long does a natural leather strap last on the Mido Ocean Star M026.629.37.291.00?

The lifespan of a natural leather strap varies depending on tanning type and usage. Quality vegetable-tanned calf offers 3-5 years with moderate daily wear. Alligator, being thicker and more resistant, can last 5-7 years. Durability increases if the watch is not worn in extreme humidity or heat conditions. To extend strap life: dry the watch if exposed to fresh water, avoid prolonged contact with heavy perspiration, periodically condition the leather with natural oils.
