I bought a Tudor 7966 Gold Filled watch. Case is out of shape but everything else including crown is good to excellent. Movement is really accurate. If I were to recase it using a 7965 case, would that be appropriate? Would it be a frankenwatch? The dimensions for the movement are the same. The 7965 is the nodate version that uses eta 2451 versus 2452 date version used by 7966. So I would put a 7966 gold markered big rose dial and hands and Tudor original 2462 (eta 2452) in a 7965 case steel case that uses 2461 (eta 2451 no date). The dimensions of movement and hand sizes are same. Thanks.
