Frequently asked questions

What is the lug width of the Mido Ocean Star M026.627.37.051.00?

The lug width of the Mido Ocean Star M026.627.37.051.00 is 22mm. This dimension is measured between the internal terminals of the case and is essential for selecting a compatible strap. You can verify it using a digital calliper positioned perpendicular to the lug shoulders, or by consulting the official brand technical specifications.

Which strap is best for the Mido Ocean Star M026.627.37.051.00?

The choice depends on usage and aesthetic preferences. For formal elegance: alligator or vegetable-tanned calf leather in navy blue or cognac brown. For sports versatility: NATO in technical nylon, dark blue or black. For intensive diving use: vulcanised FKM rubber in black, which resists saltwater and maintains flexibility at low temperatures. Milano Straps offers all these options in 22mm, ready for installation.

How do you change the strap on the Mido Ocean Star M026.627.37.051.00?

The Mido Ocean Star M026.627.37.051.00 is fitted with spring bars of 22mm diameter. To replace the strap: 1) use a spring bar tool to apply pressure on one of the bars and remove the old strap; 2) insert the new strap by aligning the hole with the lug terminal; 3) press the opposite spring bar into the opposite hole until it clicks into place. This requires no specialist tools or watchmaker skills, provided you work with care on the brushed case.

Is there an aftermarket strap compatible with the Mido Ocean Star M026.627.37.051.00?

Yes, the M026.627.37.051.00 accepts any 22mm strap fitted with compatible spring bars (standard diameter). Milano Straps offers a dedicated collection of 22mm straps in alligator leather, vegetable-tanned calf, NATO in fabric and vulcanised rubber, all carefully selected for colour and construction characteristics. Ensure that the chosen strap has a thickness of between 3 and 4.5mm at the tip for comfortable installation in the lug slots.

How long does a leather strap last on the Mido Ocean Star M026.627.37.051.00?

A quality leather strap (alligator, vegetable-tanned calf) lasts 3–5 years in regular use, with variability depending on climate, frequency of wear and maintenance. Sun exposure accelerates surface ageing; constant humidity can promote mildew if the strap is not dried. Vegetable tanning develops a natural protective patina over time, which extends life. With periodic maintenance (application of specific balm 1–2 times per year), a sturdy strap can exceed 6–7 years. If the M026.627.37.051.00 is used frequently in water, it is recommended to alternate with a rubber strap to reduce stress on the leather.
