ELKA's flight-instrument-styled 40.8mm watch with the date, launched on Kickstarter alongside the D Series in June 2022 (Monochrome: CHF 999 on the campaign, CHF 1,490 planned retail). ELKA references read <series><dial number><suffix>-<strap code>: X09 is the beige-to-black gradient dial with "old tritium" Super-LumiNova numerals, brushed nickel hands with beige lume and a beige seconds hand. The four-digit code is the strap (08xx leather, 09xx NATO, 10xx steel bracelet) and sets the price (CHF 1,569 on NATO, 1,625 on leather, 1,662 on the rice-grain bracelet). A "w" after the dial number (X01w, X15w) means no date; those are the separate X Series No Date model. X Heroes is listed on the brand store but is not yet in this file; the 25-piece Ace Jewelers Diversity editions (X11 to X14, X16) have no date and are in X Series No Date. Brand spec: 1.4404 steel case, 40.8mm, 10.80mm thick, 46.5mm lug-to-lug, screwed steel case back, chevé box sapphire with AR treatment on one (unstated) side, 50m. Whether the 10.80mm includes the crystal isn't stated; Monochrome's 2022 Kickstarter spec gave 41mm x 11.85mm and 30m, so the total height may be nearer 11.85mm. Lug width from the 20/18mm strap. Weight not published. X01 is the black dial with "old tritium" Super-LumiNova numerals, brushed nickel hands with beige lume and a beige seconds hand; X02 the khaki beige dial with black numerals and an orange Super-LumiNova track, hands as X01; X03 the blue dial with white Super-LumiNova numerals, hands with white lume and a white seconds hand. All nine X01 to X03 spec sheets name the G100 with the date at 3 and give 10.80mm thick, and the photos show the date. Thickness is left blank: ELKA's D Series sheets for the same case give 10.80 or 11.85mm, Monochrome gave 11.85mm, and no source says whether the crystal is included. The X03-0804 sheet lists a beige NATO strap, but its title ("Suede Leather Strap"), description (semi-rembordé leather with microfibre lining) and photo show the cognac strap, which is recorded; the X01-0804 sheet gives the strap as 18/16mm, likely copied from a smaller watch, against 20/18mm on the other sheets.
