Just picked this up and before I start trying to service it wanted to see if anyone has any experience with opening the case and removing the movement. Also curious up front what caliber and who the manufacturer is.

Thanks in advance--Jay (Levine98)

I have a similar watch. Carefully remove the 4 screws on the back and the caseback will detach. Inside should be a movement ring and standard setting level screw to loosen 1 and a half turns or so to pull the stem out.

Thanks. Was able to service including new mainspring. Nicely finished Certina 414 movement in a front loading case (solid case back) using a split stem—similar to several Bulovas I’ve serviced.





Nice! I have had good luck on Crotons and have this Aquadatic with an ETA 1258 first Gen auto with a oscillating weight. Had the 4 screws so is why I thought yours would be similar.DSCN51973.thumb.JPG.7a4a6a484c585c90a49c485a1fd5755d.JPGDSCN51993.thumb.JPG.cb8a121c82d659068ed5b8795de2a6c1.JPGDSCN52003.thumb.JPG.af90840c740ae27f886992fedfafd5dd.JPGDSCN52013.thumb.JPG.99a3cc05c5d486841d13781878397628.JPG
