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. 27 (Graz house regiment): brown bicolour sandwich dial, yellow small-seconds hand. Two finishes sold as separate listings, recorded as variants: IR27 (polished case with brushed bezel, sunburst dial, date at 3; EUR 1,740) and IR27 Vintage (bead-blasted case, brown gradient dial; EUR 1,500). The Vintage has no date: its listing gives time with small seconds only and its photos show no date window. 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 store's separately sold bead-blasted 316L bracelet (EUR 180, folding safety clasp) is listed as fitting the IR27 Vintage. The bronze-cased IR27 Bronze is a separate model.
