From what I've researched, the gears that modify the A7750 to the 3,6,9 configuration can be removed safely. This means the chrono will still work (with the exception of the minute dial) but the date wheel can be raised because no gear gets in the way. Think I might go down this route as it has two benefits: (1) I don't use the chrono so won't miss it, and (2) I can still show people that the chrono works as long as I stop it before 60 seconds
Thanks for the info guys - its appreciated
PS: I'l post a pic once its done
