CuSn8 bronze version of the ZX chronograph with the Seiko VK67 meca-quartz (the Valjoux 7750 version and the titanium versions are separate models). Zelos's first chronograph series, styled after the X-15 rocket plane, launched on Kickstarter in January 2018 and listed on zeloswatches.com in February 2018; every ZX product is now sold out and in Zelos's Discontinued Models collection. Zelos numbers the colourways (ZX-1 to ZX-3 titanium, ZX-4 to ZX-6 bronze, ZX-6 being the bronze Meteorite); the product text is shared by the whole series ("CUSN8 Marine Bronze or Titanium Case"), so ZX-4 and ZX-5 are identified as bronze from the photos. Zelos: "Seiko VK67 Mechaquartz". SeriousWatches lists "Date: No" for the bronze ZX-6 Mechaquartz, so the VK67's date is recorded as not shown. Zelos's Mechaquartz listings reuse the automatic version's photos, which show "Swiss Automatic" on the dial and the 7750 subdial layout; the VK67 puts the 60-minute counter at 12, the 12-hour counter at 9 and small seconds at 6, so the actual dial printing differs and no photo of it was found. Zelos gives one spec list for both movements: 43mm, "16mm Height" (not stated whether it includes the domed crystal, nor whether the thinner VK67 makes this version thinner), 49mm lug to lug, 100m, domed sapphire with inner AR, "Sapphire crystal caseback" (not confirmed for the Mechaquartz, so caseback is left blank). Lug width and a fixed CuSn8 bronze bezel per SeriousWatches's ZX-6 Mechaquartz table; the ZX-4 and ZX-5 photos show the same bronze bezel. Two-layer sandwich dial with BGW9 lume; Zelos's white-subdial lume photo (on the ZX-5 listing) shows fully lumed subdials. Sold on a Horween leather strap; Zelos's separately sold ZX bracelet is titanium, so the bracelet fields are left blank. Crown screw-down and weight not stated. Prices are the store's default "sg" option on the sold-out listings; each listing also has an "hk" option (a country-pricing app, labelled "mlveda_country") at $649 (ZX-6 Meteorite $799), not recorded. The Time Bum (October 2018) quotes $429 for a Mechaquartz ZX. The ZX-6 Meteorite Mechaquartz is listed under the URL handle "zx-5-meteorite-mechaquartz-chronograph" but titled ZX-6 and shows the bronze ZX-6 photos; it is bronze per SeriousWatches. The Time Bum quotes $649 for a Mechaquartz with a meteorite dial.
