What is this tank chronograph?

Hi folks,

This image came up from a Japanese fellow that I follow on instagram back in February. It's a photo of a page from the "Chronos" Magazine from Japan, but his original image was focused on the Nicolet watch next to this intriguing tank chronograph:



I tried asking him if he could provide another shot or more info from this page of the magazine, but the language barrier was a little much.

So, does anyone here recognize this watch?

I tried googling what I could read from the dial, but no matches came up. (Chrono-metre bap*, etc etc)

Seems like a very specialized chrono since it's laid out in 10 increments. Maybe a doctor's watch?

Any help is appreciated

There was a BAPIC SA. registered in Genf, Switzerland. An older model than this



And there is still someone with the surname Bapic involved with Audemars Piguet.

" Ms. Bapic comes from a family of watchmakers: her father is a second-generation watchmaker and her mother's family manufactured watch cases." http://en.worldtempus.com/article/audemars-piguet-bapic-new-vp-of-latin-america-7204.html

Interesting. Kind of looks like a "Y" is poking out from behind the hand though and not a "C"

But that's a possibility! I'll start throwing that in my searches.

I think you're right about it being a doctors watch. Hopefully you will have it identified soon 👍

I suspect the sub dial indicates tenths of a second.

Yeahbut, which way do the subdial and the inner subdial go? The subdial could be a "decimal", registering 1/50th of a minute. Or is it a countdown? I love puzzles 😎

That magazine seems to be published in several languages, perhaps someone here reads it in german or english.

I'll have to try to figure out what issue it came from. He didn't say and there seems to be a lot of them. I'll reach out again.
