About this entry
87% of key specs known. Missing: weight, bracelet offered.
GMT version of the Holton Automatic. Brand specs: Japanese Seiko NH34 with independently adjustable GMT hand in Elliot Brown's anti-shock system, 43mm excluding crown, 52mm lug-to-lug, 14mm thick ("no thicker than the NH35 automatic version at 14mm"), 22mm strap width, 200m (every watch tested), 316L case, 3mm AR-coated sapphire, ultra-high-grip 120-click unidirectional 24-hour bezel with a case-hardened lumed insert (1200HV per the 101-A20 page), screw-down crown at 4, C3 Super-LumiNova. Photos show the NH34's date at 4. Case finishes: black PVD (101-A20, A24), vapour-blasted steel (101-A21), frosted steel on a steel bracelet (Whiteout, archived), pale gunmetal PVD (NIVO), and on the EBINOX a whole case hardened to 1200 Vickers with a vapour-blasted finish, which the brand says smooths the surface and warms its colour. NIVO and EBINOX are offered on Zulu Alpha straps. No weight published. Prices are the UK prices including 20% VAT shown on the live product pages; the store's catalogue data holds the same prices without VAT, which is what buyers outside the UK pay (the pages say that outside the UK "prices will be displayed in local currencies and without VAT"). Pages of archived listings, marked "Archive item - no longer available", show no price, so their prices are the catalogue price plus 20%.
