So I was working on a couple DJs and thought I would show what goes into making one. This has a gen dial I picked up off ebay a while ago. I am using a Rafflesdials 2836 case set.

So the parts:

I am using a 2879 NOS Swiss low beat movement that is almost exactly the same size as a 2836. I checked before I started to make sure everything would fit. Case set comes with crown and retaining ring. I will need to add a Rolex datewheel overlay, I picked champagne.

We have two major issues. First the feet on the dial don't work with the movement. There are a couple ways to fix that. Remove the existing feet and then glue new ones one with epoxy, OR, glue the ETA spacer to the back of dial and secure with a tiny bit of double stick tape. With DJs most people pick the latter.

The second problem is fitting the datewheel. I need to glue it to the existing datewheel without gumming up the works (and put it in the right alignment).

I like to use a 5 minute epoxy on this so I can adjust stuff.

So I mix up some epoxy and sparingly apply to the retaining ring, position it on the dial and center it. I sparingly apply it to the datewheel and then position the overlay. I find that lining up the middle of the three with the stem gives me the best result. Let it dry overnight.

Using 1/8 inch double stick tape I put three small pieces on the outer edge of the movement.

Line up the dial and press onto the movement.

Now we need to put the hands on. In the time set position set the movement forward until the date just snaps over. That is midnight. Now we set the hands. I use brass tweezers as they are less likely to scratch the hands.

I have a hand setting tool but I still find a ball point pen insert to be the easiest way to set the hour hand. I set the other two with the hand set tool.

So now we need to case the movement and trim the stem.

Put the retaining ring on the stand, position the movement and drop the case over it.

Now flip it over, reinsert the stem, and put in the movement holder screws and tabs.

Now I need to measure the stem. In the winding position I press down on the crown and measure the distance between the bottom of the crown and the top of the case.

I take that much off the stem, apply blue locktite to the threads and screw on the crown, and reinsert it. Silicon grease on the back oring and screw the back on. Bam you are done!

Purdy, ain't it? In my opinion, the best money you can spend on an upgrade is a gen dial. I care nothing about a gen crystal or crown, you get pretty low payback on those. But a dial really pops

Its not just gen dials you will have the dial feet problem with. Yuki dials usually come with dial feet in the gen position so you end up clipping them off. All their hands that come with the dials are also for gen movements. Request to buy the dials without hands, its cheaper and the hands are useless.

Perfect and nice write up for building a very nice 5-digit Datejust.
I like them :)

This is a great 5-digit Datejust build Rich!

Someone was looking for a 1601 build on a different thread have you found a case with those thin lugs or would someone have to slim down a 16XXX case to achieve the right look?

No thin cases, you have to make them. Raffles has a 2824 case that is thinner than this one, but it would still need trimming down. The 2824 case is what JMB uses to make 1016 cases.

Well got me hooked on this now .. so question for the guru's as I know little about vintage datejust options for dials ... checked yuki and they appear to all be pie pan dials for datejust ,,are the Raffles dials decent until find a gen dial ? or is there another option ? ... ideally looking for a grey dial or silver

Also is there an alternative crystal that would fit this case without the cyclops ? and finally source for a roulette date wheel for 2824 / 2836 ? would this work .. ? http://rafflesdials.com/one-pc-white...-master-watch/

Some of the rafflesdials are very good. I built this one a while back:

What you linked is not a roulette date wheel. Its just red.

Nice ... dial looks good I am not OCD yet and my wallet is in agreement. Have me convinced, realized that after I linked it. I am thinking of doing a silver/grey version and can't find a roulette wheel would the red one work what do I need to ensure as it said sub which is a 40 mm case and this is 36 but both same movement ,,, ?

Thanks

Send a PM to the guy at raffles, he can tell you whether it will fit. I buy what he tells me to.
