The original Swordfish, listed by Zelos on 25 October 2018 and now in its Discontinued Models collection; it was followed by the Swordfish V2 300m Diver (August 2019, a separate model with a slim micro-adjust clasp). Zelos sold it with a Seiko NH35 without a date window (this model) or an ETA 2892 with a date at 6 (Swordfish 300m Diver ETA 2892, separate file). Case 42mm, 48mm lug to lug, 13mm thick (not stated whether that includes the crystal), 22mm lugs, 300m. Bezel: unidirectional (SeriousWatches), 120 clicks, brushed ceramic insert "with 2000 Vickers hardness" per Zelos (SeriousWatches says 1200), fully lumed; the Aquamarine has a steel insert instead, so insert material is recorded per variant. Solid end links per SeriousWatches. Sandwich dial with C3 and BGW9 Super-LumiNova; Black Sand variants have gold hands and "vintage" patina lume. Sold with a 316L bracelet with a "Quick Adjust Diver Extension Clasp" plus a Horween leather strap; clasp micro-adjust type, crown type (only "signed crown" is stated), crystal shape, AR coating, caseback and weight are not stated. Black Sand PVD has a darker PVD-coated case (from the product title and photo). Prices are the store's default "sg" option; each listing also has an "hk" option (a country-pricing app, labelled "mlveda_country") at a higher price ($499, Meteorite $749), not recorded. The product URLs say "launch special" but the pages don't say whether $349 was an introductory price.
