Thanks a lot MM... Much appreciated.
Here's the serial number: 156087
I will indeed enjoy the watch.

: Hi Mark.

: I still do a double take when I see your forum name, but I guess
: it's fine to welcome another Mark M to the fold!

: Now, here's the thing. There is no doubt in my mind that the wider
: hands were designed for the double markers. But equally, there
: is no doubt that Heuer in the 60s and 70s was a fairly
: parsimonious organisation and they were going to use those
: stocks up, come hell or high water. Also, unlike today's
: operation where an individual performs a single operation before
: sending the watch-to-be along a vacuum tube for someone else to
: perform the next operation, assembling a watch in the 70s seems
: to have been the work of fewer, maybe even a single, individuals
: and each seemed to be working from a personal stock.

: So while we give executions in the table, it's not such a hard cut
: off as that might suggest and in the real world what we see is a
: more fluid mix of characteristics. So while we might say: 12
: hour dial, double markers, wide hands, tachy at 1, we often see
: a mix and match approach and we see it often enough to be pretty
: comfortable that at least some of the watches left the factory
: that way.

: So I wouldn't panic about your watch :)

: Mark (also M) :)
