I've recently purchased this Bulova Sea King 737 (11BLC Caliber) to practice disassembly and reassembly but before i've even removed the movement from the case i have an issue. I've removed the case back and the two screws holding down the movement but i'm struggling to take the movement out of the case. There is a spacer ring holding the movement but there seems to be an additional brass c-shaped ring between the spacer ring and case with a lip which the spacer ring is underneath so there does not seem to be any obvious way to get the movement out. I've considered this may be a front loaded watch but there is no obvious markings to denote this. Has anyone worked with a similar watch and can advise how to get the movement out please. Thanks in advance. Maz My watchmaking journey!
