About this entry

89% of key specs known. Missing: weight, hardening.

USA-assembled 42mm D4 solar diver with date; the 39mm D4 (Epson VS22, no date) is a separate model, as is the Hong Kong-assembled DS4 42mm with a flat crystal. Brand spec lists (identical on both pages): 42mm, 48mm lug-to-lug, "11.6mm in height (13.7mm with crystal)", 20mm lugs, 20 ATM, 316L steel, locking screw-down crown, single-domed sapphire with AR coating (side not stated), "Japan Made Epson VS42", -10/+20 sec/month, USA assembly, 6 months' reserve from 6 hours of light. Date window at 3 in the 42mm product photos. The sizing paragraph's "case weight of 70.6 grams" is the D5 39mm figure repeated across Vaer's pages, so no weight is recorded. Crystal: the product pages say single-domed and Vaer's solar-diver journal says the D4 has domed sapphire where the DS4 is flat; Vaer's February 2026 D4/DS4 guide says both use flat sapphire. Domed kept. Lume: 20 layers of X1 W20 on the dial and W20 on the hands per the spec lists (the pages' comparison chart says 25 layers) and a "Lumed Ceramic Bezel". Unidirectional bezel and screw-down gasket-sealed caseback per the D4/DS4 guide; coin-edge bezel per the product pages; 120 clicks per the "120-Click Bezel" callout in the Meridian Black 42mm gallery infographic (an older Vaer journal post also calls the D4 bezel a ceramic 120-click unit). Solid caseback (etched wave pattern and Vaer logo) from the gallery photos. Vaer cites 1970s Rolex and Doxa military divers for the dial and bezel and the military-issue Omega Seamaster for the case. The Meridian Navy Matte costs USD 30 more than the Meridian Black in every configuration (its build selector still shows USD 449; the variant prices are used). Every D4 ships with a black FKM strap plus a second strap or a bracelet. Bracelet recorded is the Premium Steel Bracelet (+USD 90; "DS2/D4/DS4/D5 42mm" fitment): oyster-inspired flat three-piece links, removable screw links, custom-fit solid end links, quick-release pins, 20-16mm, milled clasp (bracelet page title), four micro-adjust positions at the clasp (Vaer FAQ); the Premium Jubilee bracelet (+USD 120) is the other bracelet option. Both colourways were sold out on 2026-10-21 (Navy Matte: "Next restock expected Late October"; Black: no date given). The Meridian Black 42mm listing dates from December 2022 and the Navy Matte from November 2024; whether earlier batches had today's specs was not checked, so no release year is recorded. No hardening treatment is mentioned.
