Just finished putting together my first diver build a 6309-7290.
I have a few questions for the more experienced:
The chapter ring fits, but it rotates slightly when i install the movement making it difficult to line it up perfectly. It was an aftermarket part from the Philippines and advertised for the 7040 ( I couldn't seem to find a black minute chapter ring for the 7290 anywhere, even after a few months of searching) Any way of overcoming this with the existing ring ?
The crown is popping out of the screw position. Is this possibly because the stem is too short/long or even a thread issue ?
I don't have a metal movement retaining ring or spring, are these specific to the 6309-7290 only ? I haven't been able to source one yet.
I am happy with how the watch is turning out. The only thing I want to change is the bezel and insert, the quality isn't all that good. Id like the watch to look as original as possible until I can source the genuine parts . Any recommendations on quality aftermarket bezels and inserts for the 6309 7290 i'd appreciate.
Chapter Ring: 7040 chapter rings have a slot which lines up with a tab on the dial. Does it have this slot. If so it might be that its out of position relative to the markers.
Crown: Have you changed any part of the crown assembly. Is it locked fully home.
Movement rings and springs: AM springs are available here in the UK but the only movement rings I have seen are those being sold by a breaker. I acquire these when buying breaker watches for other parts.
I will check the chapter ring tomorrow for the slot on the chapter ring but i don't remember seeing one.
The crown and stem is new, recently bought from speedtimer, and you have to cut it too fit, so i may have either cut it too short or not enough. The crown begins to catch the thread and then pops out. I may try shortening it a little more.
I will search out an AM springs and keep my eyes peeled for a movement ring in the future
If the chapter ring does not have the slot then the dial (if it has the tab) will sit high. You should be able to see this through the glass.
Sounds like the stem is too long.
The AM springs are sold by dave-e-b. I have bought many and they are not only good but also stainless steel. On this subject if you are hunting down a movement ring it may well come with the spring. The only issue with OEM springs is that they are spring steel and they do rust.
Sorry if many of my topic pictures do not appear. I decided to keep less data in the cloud should I suddenly disappear off radar.
Chapter rings are shared with 7548s and 6309s, the stem shouldn't need cutting as it is in two parts, one male base stem section screws into the crown, with a female part of the main stem that sits over a spring and washer mounted over the male stem.
The dial is fake, so it may be that there isn't a guiding tab for the gap on the chapter ring, the chapter being aftermarket may also be missing this section on the underside.
If it was me I'd maybe use it as a parts or project watch as the only thing genuine is likely the movement. Spending more money on bezels and inserts I'd suggest is better put into a complete original.
Dials turn up now and again for these, as do chapter rings, if you need a chapter ring I may have one but I'd suggest the dial is more important to track down if going the resto route. Movement spacer is the same as many 7546s, 6309, 7548s, altho the diver ones are normally equipped with a larger cut out for the case tube..you can file open the slot on 7546 metal spacers to fit if needs be.
