Strap for Seamaster Polaris Titane / Pink Gold / Chronograph

The Omega Seamaster 120M TR 378.0885 requires a strap with a lug width of 20 millimetres. This dimension is specific to this model and represents an intermediate standard between the more common 19 and 22 millimetres sizes. You can verify the exact measurement by placing a digital caliper inside the lug recess, between the two spring bar attachments.

For the rose gold and titanium two-tone of the TR 378.0885, alligator represents the most luxurious and elegant choice, especially in dark brown or cognac tones, where the regular grain pairs perfectly with the rose-gold. Aged shell cordovan offers a natural patina that evolves over time. For more sporty contexts, natural rubber or NATO fabric straps maintain coherence with the Seamaster's diving vocation.

The TR 378.0885 features classic non-integrated lugs, which facilitates replacement. The procedure requires a spring bar removal tool: insert the tool into the lateral slot under the lug, apply light pressure to release the spring, then remove the old strap. Align the new strap with the attachments and insert the spring bar until it clicks. Perform the operation carefully to avoid scratches on the case.

Yes, completely. Since the TR 378.0885 uses non-integrated lugs, any strap with a lug width of 20 millimetres is compatible. Custom handmade straps from Milano Straps are constructed specifically for this dimension, ensuring comfort and security without any aesthetic compromise.

The durability of a leather strap depends on material quality, tanning and frequency of wear. A high-quality alligator or shell cordovan strap, maintained with care and worn daily but not during intense water activities, typically lasts between 3 and 5 years. Exposure to moisture and saltwater (given the Seamaster's aquatic spirit) accelerates ageing. Milano Straps offers an 18-month warranty on all custom straps.
