Aquis Date 01 733 7730 4159-07 8 24 05PEB 43.5mm

Ref 01 733 7730 4159-07 8 24 05PEB is a later black-dial Aquis Date 43.5 on the steel bracelet, from the 4159 dial code rather than the earlier 4134. Visually it’s very close to the 4134, so read the full reference on the caseback paperwork when you’re matching orders.

For the end customer it’s a black Swiss diver on a bracelet — the most predictable sell in the category. Black dial, black ceramic bezel, applied indices with plenty of lume, date at 6. Retail reference runs about $2,300–$2,500.

Underneath: Oris Calibre 733 automatic (38-hour reserve), 300m water resistance, screw-in crown, domed sapphire, display caseback, folding clasp with diver extension.

Treat it as interchangeable with the 4134 bracelet for most buyers. Collectors who care about the dial code will ask; everyone else just wants the black one.
