Strap for Seamaster Aqua Terra 150M Master Chronometer 43 Worldtimer Stainless Steel - Ceramic / Green / Bracelet

The lug width is 21mm. This dimension is specific to this model and must be measured between the inner shoulders of the lug. Any aftermarket strap must respect this exact width to ensure a perfect fit without play or forcing.

The choice depends on intended use. For formal elegance we recommend black alligator or brown vegetable-tanned calf; for versatile daily wear, vegetable-tanned calf in neutral tones; for sports and water use, NATO canvas or FKM rubber. Natural alligator remains the most refined solution, enhancing the geometric pattern of the back.

The Omega Aqua Terra 220.30.43.22.10.001 uses integrated lugs with spring bar mechanism. Obtain a quality spring bar tool. Position the watch face down, gently compress the spring bar with the tool to disengage it, remove the old strap, insert the new one aligning the holes and release the spring. Avoid sudden pulls that could damage the lugs.

All straps with 21mm lug width are compatible. On milanostraps.it you will find a selection of handcrafted straps in alligator, calf, shell cordovan and rubber, all perfectly sized for this model. Atelier Casati Milano also creates custom solutions by appointment.

A quality leather strap, with vegetable tanning, typically lasts 3-5 years with moderate daily use. Durability depends on frequency of wear, sun exposure, humidity and care. Alligator resists longer than calf. FKM rubber is more resistant over time, ideal for humid environments. Straps from milanostraps.it include 18-month warranty against manufacturing defects.
