Need a new movement for the Chronmat I've been told go with a 7753,...will l need to modify anything or will it bolt in so ti speak? Also is 300 euro a decent price for a 7753?
The 7753 will fit into the case but the Asian eta7750 has a different hole size on the hands for the subdials .So you will need a experienced modder that can crimp down the hole to make it fit on the Swiss 7753 .Other than that will everything else drop in .
before you move forward, think if that watch is worth investing $700+ into. The chronograph seconds hand is a different diameter so the most stable option is harvest the handstack from the existing movement.
