Aquis Date 01 733 7653 4135-07 4 26 34EB 43mm

Ref 01 733 7653 4135-07 4 26 34EB is the blue Aquis Date from the 43mm generation — the case Oris used before the 43.5mm 7730 replaced it. The quickest way to tell them apart is the lugs: this 7653 case uses a 26mm integrated strap fitting, which gives it a chunkier, more tool-like profile.

There’s a following for the older 43mm Aquis. The wider strap and shorter lug-to-lug make it wear more compact than the number suggests, and some buyers actually prefer it to the newer case. Retail reference sits around $1,950–$2,200, a little under the current 43.5mm models.

Specs: 43mm stainless steel case, blue ceramic bezel insert, blue sunburst dial, Oris Calibre 733 automatic with 38-hour reserve, date, 300m water resistance, screw-in crown, domed sapphire, display caseback. Note that the 26mm rubber strap is specific to this case — 24mm Aquis straps won’t fit.

A good value play. Price it just under the 7730 blue and it gives the customer a reason to choose.
