About this entry

80% of key specs known. Missing: lug-to-lug, hardening, bracelet offered.

Land collection model for k.u.k. Infantry Regiment No. 73 (Egerland): "mud-streaked" off-white sandwich dial with red lume on indices and hands; date at 3. Two finishes sold as separate listings, recorded as variants: IR73 (316L with black PVD; EUR 1,740) and IR73 Vintage (bead-blasted steel per its spec table and description; EUR 1,500). Brand spec (product page): 44mm without crown, 13.8mm total height, 22mm lugs, 134g on the leather strap, 316L steel case with an 8-screw bezel and an 8-screw 316L steel caseback (display window, from photos), screw-down crown, 300m (30 ATM), domed sapphire crystal with inner AR coating, sandwich dial, Super-LumiNova on indices and hands. Sellita SW360-1 (31 jewels, 28,800 vph) in Elaboré grade, rhodium-plated and decorated. Limited to 200 numbered pieces (each listing states 200; whether the finishes share one run is not stated). Supplied on a leather strap with pin buckle. Lug-to-lug is not stated and no review was found. A 2019 press release announced the Land series as 44mm and limited to 100 numbered pieces per model, shipping from 23 April 2019; the current listing's figure is used. Release year not confirmed. The IR73 Vintage listing reuses the black PVD IR73's photos only, so no image is attached to that variant; its finish follows its text.
