Strap for Seamaster Aqua Terra 150M Master Chronometer 38 Stainless Steel / Blue / NATO / US Paralympic

The lug width of the Omega Aqua Terra 220.12.38.20.03.003 is 19mm. This technical specification indicates the distance between the two lateral lugs of the case and determines which strap width to fit. All compatible 19mm straps will adapt perfectly to this model.

For the Aqua Terra 220.12.38.20.03.003, the brown alligator strap (medium or dark) represents the classic choice that enhances the sporty sophistication of the stainless steel case. Alternatively, vegetable-tanned calf leather offers daily versatility with natural patina over time. NATO straps are ideal for intense marine use.

To change the strap, you need to remove the lug module through the two lateral pressure holes using a specific spring bar remover tool. Insert the tool under the spring, press slightly downward to release the pin, then extract it. Repeat on both sides. Insert the new strap by aligning the internal pins with the case lugs and press until the locking click is felt.

Any universal strap in 19mm width is compatible with this model. MilanoStraps offers an exclusive collection of handcrafted 19mm straps, customizable in leather (alligator, calf, shell cordovan), color, size and thread, with 18-month warranty.

A quality leather strap (alligator, vegetable-tanned calf) typically lasts 3-5 years if worn daily and maintained regularly. Shell cordovan can last over 7-8 years thanks to fiber density. Wear depends on climate, frequency of use and preventive care such as treatment with colorless cream every 4-6 months.
