Strap for Seamaster Aqua Terra 150M Master Co-Axial 34 Sedna Gold / MOP

The lug width of the 231.53.34.20.55.001 is 20mm, measured center-to-center between the lugs. This specification is essential to ensure strap compatibility and proper functioning of the deployment clasp. We recommend always verifying this measurement before ordering an aftermarket strap.

For an Aqua Terra 231.53.34.20.55.001 in Sedna Gold, we recommend black alligator or cognac brown, which balance sportiness and elegance. Shell cordovan is excellent for those who desire a patina that evolves over time. Vegetable-tanned calf offers a refined tactile feel and adapts well to the formal-sporty context.

To change the strap, you will need a spring bar tool. Position the watch on a soft surface, locate the lateral pins under the lugs, gently insert the tool to extract the retaining pin, then slide off the old strap. Repeat on the other side with the new strap. If you lack experience, consult a qualified watchmaker.

Yes, provided the lug width is exactly 20mm. We recommend straps of verified quality to ensure perfect compatibility and avoid damaging the case lugs. Specialized suppliers such as Milano Straps offer handcrafted straps tested on this specific configuration.

Durability depends on the material and usage. A quality alligator strap offers 3-5 years of regular wear. Shell cordovan can last 5-7 years thanks to its structural density. Vegetable-tanned calf typically lasts 2-4 years. Proper maintenance—regular cleaning and conditioning—extends the lifespan of any strap.
