Be careful an try not to use the chrono function too often.
The subdial at 3 o'clock tend to have issue of the hand not reseting to zero on the A7753 movt after a while. You will also see that the hand will not stay put at zero position for long and will offset slowly to either one direction.
If yours do not have the problem stated above, then the next mod you want to consider is to strip the existing AR (too purplish) and send to Taka for single sided AR (which is colorless).
Enjoy the watch
