Heuer Super Professional 1000M 840.006
(And yes, the word “super” is on the dial 😀 )
It’s a 2892 A2 25j movement. The watch design is a carryover from the pre-TAG days at Heuer (TAG acquired Heuer in 1985). A serious tool watch, looks the part and is what it appears. Heavy, easy reading, manipulatable with gloves, up to doing deep diving.
