Hi all,

last year, looking for a modern TH watch (an Autavia CY2110 modern re-issue, yes, I know, not many TH lovers here...), I stumbled upon a NOS Calculator 150.633N at an italian TAG Heuer AD (and Heuer before), and until now I worn just a couple of time to show it at job. But, after buying some straps from Giuliano for other references, the appetite took me also for the Calculator, so I asked him to prepare a black simil-Corfam strap with orange stitching to match its beautiful orange hands.
The strap is 22/18mm, with a 18mm SS Heuer buckle (beta stamped), I don't know if originally the Calculator had a 22/16 or a 22/18, but the 22/18mm size is ideal because the case is really big....

The watch is a 1972 one (the original steel bracelet has written "4972" on the clasp), serial is 2661XX, black dial with red measure units on the inner bezel.

Before the images, I want to really thank Giuliano for his wonderful strap, it's almost a pity to wear it ;-)

PS: sorry Arno MH if I used your beatiful book as backgrounf for some images...
