Frequently asked questions

What is the lug width of the Mido Ocean Star M026.430.17.051.00?

The lug width of the Mido Ocean Star M026.430.17.051.00 is 22 millimetres. This measurement is taken internally, between the inner edges of both lugs. This is the correct reference for selecting compatible straps without risk of visual imbalance or strap slippage.

Which strap is recommended for the Mido Ocean Star M026.430.17.051.00?

For the Mido Ocean Star M026.430.17.051.00, straps in alligator (for evening elegance), vegetable-tanned calf leather (for vintage aesthetic), regenerated NATO in navy or grey tones (for versatility), or FKM rubber (for certified diving use) are recommended. Choice depends on intended context: sporty, professional, or casual wear.

How do you change the strap on a Mido Ocean Star M026.430.17.051.00?

To change the strap: position the watch with lugs facing upward, use a spring bar tool to compress the internal spring mechanism of the spring bar (the pin securing the strap), remove the pin from one lug, slide the old strap out of both lugs, insert the new strap (22mm lug width) by sliding one spring bar through the passage, then reinsert the pin into the opposite lug until you hear a click of security.

What is the aftermarket strap compatibility for the M026.430.17.051.00?

All straps with 22mm lug width are compatible with the Mido Ocean Star M026.430.17.051.00, regardless of material (leather, NATO, rubber, fabric). It is essential to verify that the internal passage of the strap has an internal width consistent with the lug shoulders, to prevent slipping or accelerated wear. Milano Straps offers 22mm straps tested for this specific dimension.

What is the lifespan of a leather strap for the Mido Ocean Star M026.430.17.051.00?

A leather strap (alligator, calf, shell cordovan) worn daily lasts approximately 18–24 months, depending on ambient humidity, frequency of wear, and tanning quality. Vegetable-tanned leather develops natural patina over time, extending aesthetic appeal. Rubber or NATO straps have longer lifespan (36+ months), with wear primarily visual rather than structural.
