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) :)
