Strap for Seamaster Aqua Terra 150M Co-Axial 44 Chronograph Stainless Steel / Ivory / Bracelet

The Omega Seamaster Aqua Terra 231.10.44.50.09.001 has a lug width of 20 millimetres. This dimension is standard for this model family and should be verified by measuring between the internal attachment points of the case. On milanostraps.it you will find the entire collection of 20mm straps compatible with this watch.

It depends on your use and personal style. Dark blue alligator amplifies the marine and formal character; vegetable-tanned calf offers natural ageing and sustainability; shell cordovan guarantees exceptional durability. For frequent water use, we recommend FKM rubber or NATO fabric. The Casati Milano atelier will guide you in your choice by visiting you by appointment.

The Aqua Terra features straight lugs with removable spring bars. Use a dedicated watch tool (spring bar tool) to extract the bars from their seats: insert the tip into the lateral slot, lift gently and the bar will disengage. Repeat on both sides. Install the new strap by reversing the procedure. If you are not experienced, the Casati Milano atelier will perform the change with professionalism.

Yes, provided it respects the lug width of 20 millimetres and the overall length is suitable for your wrist. The milanostraps.it straps are constructed specifically for this width and are fully compatible with the case. Custom sizing guarantees a perfect fit.

It depends on the material and use. A superior quality alligator or calf lasts 3-5 years with ordinary maintenance (no prolonged exposure to salt water). Shell cordovan can last 7-10 years. Natural ageing is part of the charm of leather: the strap develops patina and character. The 18-month warranty from Casati Milano covers manufacturing defects.
