Strap for Seamaster Aqua Terra 150M Master Chronometer 38 Stainless Steel / Grey MOP / Bracelet

The lug width of the Omega Aqua Terra 220.10.38.20.57.001 is 19 millimetres. This measurement represents the space between the two lugs of the case and determines the compatibility of any replacement strap. You can verify this dimension by consulting the Omega warranty booklet or by contacting us directly to confirm the measurement before purchase.

For the Sunburst Teak dial and grey-blue lume, we recommend alligator straps in dark brown or cognac tones, or vegetable-tanned calf leather in bourbon finish. Alligator offers durability and formal sophistication, ideal if you wear the watch in professional settings; vegetable-tanned calf is softer and develops a fascinating patina over time. Anthracite grey or black rubber remains the sporty choice for diving or water activities.

The strap is changed by releasing the spring bars that connect the strap to the lugs of the case. You only need a specific tool (spring bar tool) or even a small flat-head screwdriver. Insert the tool into the thin slot next to the spring pin, push gently to free the pin from its housing, then remove the old strap and insert the new one making sure the pin clicks firmly into position. The operation takes just a few seconds and can be performed at home.

Any strap with a 19 millimetre lug width is compatible with your Omega. On milanostraps.it you will find a wide selection of 19mm straps in alligator, calf, shell cordovan and rubber, all ready for shipping and customizable in sizes, initials and thread colour. You can also order a made-to-measure artisanal strap from the Casati Milano atelier.

The lifespan of a leather strap depends on the material and usage. A quality alligator strap, worn daily but properly maintained, generally offers between 2 and 4 years of wear before showing significant signs of deterioration. Vegetable-tanned calf has a similar lifespan but ages more rapidly aesthetically. Vulcanized rubber is more durable (5-7 years) but less elegant. We recommend rotating straps to distribute wear and storing them in dry environments away from direct light. The 18-month warranty on artisanal straps from Casati Milano covers manufacturing defects.
