Automatic version of the PRS-40 (designed by Giovanni Moro, first sold as a quartz watch in 2014), with NATO stock number 6645-99-994-7232. Product page: 316L bead-blasted steel, 40.2mm across the centre of the case and 27mm wide at the lugs (the importer recorded 27mm as the diameter), 54.7mm lug-to-lug, 12.25mm to the top of the crystal, 22mm lugs, anti-magnetic 4,800 A/m with an anti-magnetic movement cover, 100m, screw back, 88g head only; flat sapphire 30.5mm x 1.8mm with AR on the underside; semi-matt black dial with lumed hour markers and lumed skeleton ("ladder") hands, Super-LumiNova C3. Seiko Instruments NE15 C (6R15), 24 jewels per the page, 21,600 bph, about 50 hours; the dial photos show no date window, so the NE15's date is not displayed. 22mm black NATO strap. The chronograph versions (VK61 two-register, VK67 three-register) are separate models. Sold out on 2026-10-25 with no restock note, so status is unknown.
