Strap for Seamaster Aqua Terra 150M Shades Master Chronometer 34 Stainless Steel - Moonshine Gold / Champagne / Bracelet

The lug width of the 220.20.34.20.08.001 model is 16 millimetres. This measurement should be taken internally between the metal lugs of the case, perpendicular to the watch's axis. Omega has calibrated this dimension to maintain harmonious proportions with the 34 millimetre case, avoiding visual effects of overhang.

Vegetable-tanned alligator is the ideal choice for this model's elegant-sporty vocation. The natural texture of the scutes harmonises with the blue dial and Moonshine Gold, while vegetable tanning ages nobly, developing patina over time. For frequent maritime environments, European shell cordovan offers superior natural water resistance.

Use a digital calliper or flexible ruler. Position the instrument perpendicular to the watch's axis and measure the distance between the inner edges of the metal lugs, excluding the case body. Do not confuse this measurement with the total opening of the gap: it must be accurate to half a millimetre.

Yes, provided they are constructed to respect the 16mm lug width specification. A quality strap made with adequate internal keeper and proportionate buckle or deployant clasp fits perfectly. We recommend straps of artisanal manufacture where the lugs are made with millimetric tolerance, not those from mass industrial production.

A superior quality leather strap (alligator, shell cordovan, tight-weave calf) worn daily on a 34mm with 16mm lugs lasts on average 3-5 years before showing visible wear at the stitching. Exposure to salt humidity and chlorine reduces this interval; vegetable tanning resists better than synthetic finishes. Casati Milano guarantees 18 months on custom-made artisanal straps.
