Thanks for your replies!
The amazing thing on this is that this watch is reaching US$2.5k at the auction!
Have you noticed that, if I'm not mistaken, registers are mounted wrong? In all 7736 based chronos I've seen the 60 min register is @ 9'o and the 30 min is @ 6'o...

: Yep, I'd go with wrong dial rather than redial as the markers are
: incorrect too. All the hands are wrong - the chrono hand on the
: 60 minute register isn't far off, but should of course be white
: against a black register. The brushed finish on the case looks
: to have been completely polished away - chances are that means
: the serial and reference numbers are gone too. So a parts watch
: if you happened to have the parts sitting around... the Tachy
: ring is usable at least!
