This is an extremely nice microbrand homage to the 1960s Omega Seamaster 300 “Big Triangle.”
Full specs: 40mm x 47mm, 13mm thick, 20mm lugs, triangle dial, no date, sapphire crystal, sapphire bezel, ETA 2824-2 mvmt, solid endlinks on full solid steel bracelet.
Full kit, currently sized for 7.5 inch wrist but comes with all original links (two extra) plus a quick adjust ratcheting clasp which is one of the nicest I've seen. Worn sparingly, has very minor wear signs, light scratching in usual spots. Sapphire is blemish free. ETA 2824 appears to be keeping excellent time, just clocked it at +4 seconds per day.
Asking $650 shipped anywhere in the U.S. only. Thanks for looking.
