Strap for Ocean Star Tribute Gradient Stainless Steel / Red

The lug width of the Mido Ocean Star M026.830.17.421.00 is 21mm. This dimension corresponds to the internal distance between the case lugs. For verification, use a calliper positioned perpendicularly across the lug, excluding the spring bar mechanism. This measurement is incompatible with standard 20mm or 22mm strap options.

To preserve the model's sport-nautical identity, we recommend vegetable-tanned calf leather in burgundy or navy, alternatively a cotton-polyester NATO. For formal occasions, grey pearl or black alligator offers maximum aesthetic refinement. In intensive aquatic environments, Tropic rubber provides complete water resistance and minimal maintenance. All materials must be fitted with 21mm spring bars.

Remove the watch from your wrist. Using a spring bar tool, gently press the spring mechanism downward whilst simultaneously sliding the old strap away from the case lugs. Insert the new 21mm strap ensuring the spring bar clicks into its housing. Verify the lug is centred on the case. This procedure requires 2-3 minutes and only a spring bar tool.

Yes, any strap equipped with 21mm spring bars is fully compatible with the Mido Ocean Star M026.830.17.421.00. Spring bars are standard components and the case accepts any lug width of this dimension. Verify the strap was manufactured for 21mm measurement—not 20mm or 22mm. On milanostraps.it you will find artisan straps tested for this specification.

A quality calf leather strap, with minimal maintenance (rapid drying after water contact, conditioning balm every 6-8 months), maintains structural integrity for 3-5 years of daily wear. Alligator leather, owing to its natural fibre density, reaches 5-7 years. Accelerating factors: constant humidity, repeated chlorine exposure, lack of post-immersion drying. A NATO strap in synthetic material resists 7-10 years without significant degradation.
