Changing DWO on ARF Dj41

[bettoban]

Hi guys, i'm trying to understand what DWO use on an ARF 116334. Someone says that TC dwo will properly fit aligned on dj41's dial, someone says it doesn't and that it will need a gen 3235 dw (that should be a bit bigger). I wouldn't lose money and time searching for the wrong part, hope someone will help.

The DJ41 uses a larger diameter DW than the 40mm Rolexes use. This is what your DJ41 will look like with the standard size (including TC) overlay

Coincidentally, the DG2813 movement uses the correct size DW for the DJ41. But it's fonts are usually bad. That's what you see on the 2nd pic, on top of the 2824 movement.

There is no such thing as a gen overlay. You can use a gen DW as an overlay, if certain space constraints like dial clearance can be met or modded. Finding a gen DW this size will be next to impossible (I've tried).

Best bet is to have a TD source a Noob DJ41 DW. Even then you will likely have to sand the teeth ring off it to use it as an overlay.

Am i right in thinking u can pick up a gen 3135 dw and modify it to use as an overlay on the arf datejust 2824?

sorry for the noobness

im waiting for the datewheel to arrive and the eta 2824 than it will go to the modder
also bought a gen crystal and have the fluted bezel plated white gold

would be nice if u do a thread about ur mods as soon as u start , thought also about gen ETA and DW but didnt knew wich one could fit properly with the corectt font due to the size.
hope everything works out for u

How will it be modded? The gen DW overlaid in the 2824 movement? I am aiming to do exactly this. Whats did the gen crystal set you back mate also?

I am also waiting on my ARF 41, as well as for my gen DW ( 3235 ) from Banana Split . Would I need a different 2824 eta? or can it be overlaid on the movement that comes with the watch? Also would love to know if there are some modders here that would do this...

The gen DW will have to be glued on top of the 2824 DW and for all intents and purposes will become a DWO. The 2824 DW used as a base does not matter, it can be a gen ETA DW, a rep ETA DW, whatever. If it's a rep ETA DW, it likely already has a rep ROLEX DWO glued on that will be removed first.

The gen DW has a very different shape than a rep ROLEX DWO primarily because it has teeth. It's also going to be thicker because it normally functions as a DW and needs to be thick enough to be pushed into position by the date finger. Some modding will undoubtedly be necessary to make it work in a 2824, which has much less clearance between a DWO and the backside of the dial than a 2836 does. Also, the motion works cover has a screw on it that needs to be cleared by the DWO.

Some mods that may be performed to make a gen DW work as a 2824 DWO include:

Removal of rep DWO
Sanding down the ETA DW
Sanding down the underside of the gen DW
Cutting off the teeth from the gen DW
Adding a dial spacer to the underside of the dial to provide more clearance

ETA DW

Rep Rolex DWO

Gen DW vs NOOB DWO

Dial spacer

You should seek an experienced modder to do this for you. At all costs try to make the gen DW work without modding it, it is expensive. I don't see that happening in a 2824, but exhaust all possibilities before altering a gen.

Thanks for this mate, this is the best explanation i have read.

My smith told me to get a 2836 dw which will swap out with the 2824 and then overlay it with the gen 3235. I have no clue about modding, but he is absolutely on the ball. If this is the case how/where would i source a 2836 dw? I am tempted to just go for a noob overlay to save cash as the font isn’t bad at all - again where would i source?

A 2836 DW will not fit in a 2824, even without an overlay. The issue that arises comes from the difference in stem height. Stem height is the distance from the center of the stem hole to the underside of the dial (dial seat).

ETA stem heights

2824 - 1.8mm
2836 - 2.25mm

The reason for the extra stem height in a 2836 is to provide room for the daywheel. The 2836 DW has a taller stairstep tooth ring so it can sit nearly flush with the daywheel. A 2836 DW in a 2824 case will not clear the underside of the dial without a greatly thicker dial spacer or an additional dial spacer like I showed previously. This would force the movement to sit lower in the case, which would likely make the stem hole not mate properly with the tube, and it would definitely make the DW look sunken and overmagnifed due to increased distance from the cyclops.

Noob does make good DWs and DWOs. The normal Noob DWO like I showed earlier is not a large enough diameter to fit a DJ41 and Noob does not make a DJ41 DWO AFAIK. Your can source a Noob DJ41 DW from a TD. Their willingness to get you one depends somewhat on your established relationship and how big your order is (buy a watch too). There's not a lot of profit in small parts sales, TDs do it mostly as a courtesy for customers.

You may get lucky and a Noob DJ41 DW works 1:1 in an ARF DJ41, the teeth are correct. But the numerals might not align exactly with the date window and you might have to sand the tooth ring off the Noob DJ41 DW and use it as a DWO. Same concept as using a gen DW as a DWO.
