A military diver2019 Sinn EZM 3 (日本人又稱沈默的艦隊)special design for German police force . ETA 2842-3 is common n honestly can’t compare w my 156 Lemania 5100 or 103 7750. But because of anti magnetic 80000a/m it becomes special (cause hard to make a 80000a/m w water resistance to 50 bar) and very accurate . Plus functionally -45 to +80 degree , 500 meter, dehumidifying technology ( light blue means up to 50 percent saturation still) it is definitely a military watch . Prefer 3 more than 3F coz latter one only 200m water resistance.
Full set w certicate, manual , full links plus an extra NATO strap . Overall 90 percent condition w minor scratches ( mostly on the bracelet n back case ) . Very accurate. Sell as it is. HK goods bought in LS collection
