Strap for Oris Aquis 01 733 7789 4157

The lug width is 23mm. This measurement must be verified by positioning a digital calliper perpendicularly between the two lugs of the case, measuring from centre to centre internally, excluding any case protrusions. It is a non-standard measurement in contemporary watch design, therefore the availability of aftermarket straps is more limited compared to traditional 20mm or 22mm widths.

This depends on primary usage. For frequent diving, a vulcanised rubber or NATO strap offers maximum practicality and humidity resistance. For transitions between marine and urban environments, a shell cordovan strap with vegetable tanning develops a fascinating patina over time. A vegetable-tanned calf leather strap in cognac tone represents the ideal versatile compromise, maintaining technical legitimacy whilst introducing sophisticated visual character.

Strap change requires a specialised tool (spring bar tool). Position the tool in the small lateral grooves of the lugs, apply downward pressure to release the pin. The pin should slide smoothly—do not force. Extract the pin completely, remove the old strap, align the new strap with the lugs, reinsert the pin until the locking click. Verify strap stability before wearing the watch.

Yes, provided the strap is specifically constructed for 23mm lug width. Several artisanal ateliers, including Milano Straps, offer straps in vegetable-tanned leather, shell cordovan, alligator and synthetic materials compatible with this configuration. Construction quality determines precise fit and long-term durability; we recommend specialised suppliers who understand lug width measurement protocols.

A high-quality artisanal leather strap with vegetable tanning typically lasts 3-5 years with moderate daily use (not frequently exposed to prolonged immersion). Prolonged humidity accelerates ageing; marine salt exposure requires rapid drying and preventative treatment. A vulcanised rubber strap has superior lifespan (5-8 years), whilst woven NATO can last up to 10 years if properly stored. Regular maintenance (conditioning with natural creams, rapid drying after water contact) significantly extends lifespan.
