Strap for Seamaster Aqua Terra 150M Master Chronometer 34 Sedna Gold / Diamond / MOP / Bracelet

The lug width is 16mm. This dimension represents the space between the two lugs of the case where the strap is inserted. Make sure your strap has exactly 16mm lug width to ensure perfect fit.

It depends on your usage and aesthetic preferences. Burgundy or dark brown alligator is the classic choice for this Sedna Gold model, delivering elegance without compromise. Shell cordovan offers tactile density and develops a unique patina over time. Vegetable-tanned calf leather is ideal for those seeking contemporary minimalism.

Get a spring bar tool. Position the small hook at the end of the spring bar and press gently inward toward the case center simultaneously. The spring bar will retract, allowing you to remove the lug. Repeat on the other side. To insert the new strap, align the lug holes with the spring bars and press until you hear the click.

Technically yes, as long as they have 16mm lug width. However, verify that the thickness is not excessive: the Omega Aqua Terra has slightly slim lugs, so straps over 3.5-4mm thick could create insertion difficulty. We recommend artisanal quality straps with controlled thickness.

A high-quality vegetable-tanned or alligator leather strap lasts 3-5 years with daily wear, depending on frequency of use and perspiration. Shell cordovan, thanks to its density, tends to last longer. The main abrasion occurs in the wrist contact zone. To extend its life, alternate straps and store them in dry environments.
