Aquis Date 01 733 7653 4159-07 4 26 34EB 43mm

Ref 01 733 7653 4159-07 4 26 34EB is another black-dial Aquis Date 43, using the 4159 dial code. Next to the matte 4154 it’s very close; the reference number is how you tell them apart in paperwork.

From the customer’s side, this is a black 300m Swiss diver on rubber for around $1,950–$2,200 retail. That’s an easy pitch. The 43mm case with its 26mm strap feels robust without being oversized.

Inside and out: stainless steel case, black ceramic bezel insert, Oris Calibre 733 automatic with 38-hour reserve, date at 6, screw-in crown, domed sapphire crystal, exhibition caseback.

If you’re choosing between the 4154 and 4159 for stock, there’s no real demand difference. Carry whichever is available and price them together.
