White-dial design variation of the Smiths Military PRS-29, after the 6B/159 pilot's watches supplied to the Air Ministry in WW2. Product page: 316L brushed steel, 36mm, 46.8mm lug-to-lug, 11.1mm to the top of the crystal, 18mm drilled lugs with shoulderless spring bars, soft-iron dial and full anti-magnetic cage (20,000 A/m), 100m, 51g head only, screw back; sapphire box crystal 31.5mm across, 1.5mm thick and 3.6mm high with AR on the underside; semi-matte vintage white dial with black printed numerals, heat-blued steel hands, no date. The page lists no lume for this dial, so lume is left blank. Movement: "ETA 2801-2, Hand Winding", Swiss Made; the page says the 2025 issue of the PRS-29AM and PRS-29A uses the ETA 2801 and that it "probably won't feature again in either of the PRS29 models", so a later batch may have another caliber. NATO stock number 6645-99-515-2365 (the same number is printed on the PRS-29A page). Case and strap made in Hong Kong. Sold out on 2026-10-25, "Next Availability Spring 2027 (Date TBC)".
