The Aquis 01 733 7787 4138-07 8 22 04PEB, seen from the bench

The Oris Aquis Date 43.5 Taste of Summer Watermelon Red model 01 733 7787 4138-07 8 22 04PEB embodies Swiss diving instrument design with a 41.50 mm stainless steel and ceramic case and Oris 733 caliber movement. Water-resistant to 300 metres, it features a unidirectional ceramic bezel, reflective dial with wave pattern, and date window. The 22 mm lug width is engineered for medium-large wrists without visual imbalance relative to case diameter.

Frequently asked questions

What is the lug width of the Oris Aquis 01 733 7787 4138-07 8 22 04PEB?

The lug width measures 22 millimetres. To measure accurately, position a digital caliper between the two lugs: the horizontal value provides the precise dimension. At 22mm, this width is proportioned to the 41.50mm case diameter and accommodates structured straps while maintaining visual balance.

Which strap is best suited for the Aquis 01 733 7787 4138-07 8 22 04PEB?

Selection depends on intended use. For formal elegance, Mississippi alligator with vegetable tanning offers natural grain and patina development. For daily versatility, Hermès vitello or Tannerie d'Annonay leather provides resilience and tactile narrative over time. For intensive aquatic environments, Italian regenerated NATO fibre or FKM rubber on stainless deployante offer certified hydrophilic resistance.

How should I change the strap on the Aquis without damaging the lugs?

Use a manual spring bar tool, not a mechanical punch: insert the bifurcated tip beneath the pin, applying downward pressure to release the internal spring. Work on a soft surface such as microfibre cloth to prevent micro-scratches on case corners. The spring diameter corresponds to 1.8mm: verify that the new strap features compatible pins before replacement.

Are aftermarket straps compatible with the reference 01 733 7787 4138-07 8 22 04PEB?

Yes, any strap with a 22-millimetre lug width is physically compatible. Verify, however, that the pins meet standard specification (1.8mm diameter): some manufacturers employ different tolerances. Italian artisanal straps from MilanoStraps are constructed to certified pin standards compatible with all Oris Aquis cases.

What is the lifespan of a leather strap on the Aquis with daily use?

A quality leather strap (alligator, vegetable-tanned vitello) lasts 3-5 years with daily use, extending to 7+ years with rotation amongst multiple straps. Lifespan diminishes with exposure to perspiration, chlorine, and unprotected UV radiation. Applying neutral conditioner every six months (not mink oil) and rapid drying after prolonged water contact significantly extend operational life.
