Strap for Seamaster Aqua Terra 150M Master Chronometer Small Seconds 38 Stainless Steel / Green / Bracelet

The lug width of the 220.10.38.20.10.001 model is 19mm. This dimension represents the internal space between the lugs of the case. To verify strap compatibility, use a digital caliper positioned perpendicularly on the contact zone between lug and strap: the distance must be exactly 19mm.

Deep black alligator represents the classic choice for this model, creating an elegant contrast with the steel case and blue dial. Alternatively, vegetable-tanned Taurillon calf offers superior versatility, developing a patina that dialogues with the natural aging of the watch. For a more technical approach, a cordura NATO strap respects the model's sporting vocation while maintaining a discreet profile.

The Omega Aqua Terra 220.10.38.20.10.001 uses a fixed lug system. To replace the strap, you must remove the spring bars using a specific tool (spring bar tool or watchmaker's tool). Position the tool end under the spring bar itself, press upward to compress the spring, then extract the bar. Repeat the operation from the other side. Once the original strap has been removed, insert the new one following the reverse procedure.

Yes, any strap with a 19mm lug width is compatible with the 220.10.38.20.10.001. However, construction quality and materials vary significantly between manufacturers. An artisanal strap with thickness and texture calibrated for this specific model guarantees superior visual proportion and comfort compared to generic industrially-produced straps.

A quality leather strap (alligator, calf, shell cordovan) on a watch like the Omega Aqua Terra lasts approximately 3-5 years with daily use, varying according to humidity exposure, frequency of use and maintenance. A strap made with vegetable tanning ages gradually, developing patina and aesthetic character. A cordura NATO textile strap has a longer lifespan, up to 7-10 years, thanks to the inherent resistance of the material and the absence of organic materials subject to degradation.
