Zelos Swordfish 42 Titanium

Zelos was founded in 2014 by Elshan Tang, a mechanical engineering graduate of the National University of Singapore, and the Swordfish is its everyday diver. This 2025 titanium run has a titanium case 42 mm across, 48 mm lug to lug and 12 mm thick, rated to 200 m, on a titanium bracelet with Zelos' updated quick-adjust clasp. It runs on Seiko's NH35 with a date wheel made for the watch, under a flat sapphire. Four dials were made, from teal with a grey ceramic bezel to the Blood Moon, a maroon meteorite dial on a DLC-coated case and bracelet, and the teal and cherry fumé Sakura versions list at $449. The 2020 Swordfish Ti 42mm shared the footprint but was 13 mm thick and rated to 300 m. Worn & Wound, reviewing a steel Swordfish of the same size in 2019, found it wore reasonably for 42 mm. Every 2025 titanium dial now shows as sold out on Zelos' store while the listings stay up.
