Date wheel interchange

[jmb]

Are the physical date wheels interchangeable between 2836-2 and 2824 movements?

[FxrAndy]

no the 2836 has the thicker date wheel because of the day date mech

but you could clue it on top of the 2824 if you are using a spacer.

thats the way I want to go if I ever get my hands on any white Rolex-1680-flattop-3-open-6+9-working-on-a-2824-movement-date-disc, which apprears harder than I thought. Actually I am unable to find any :-(

It depends on which way you are going.

You can install a 2836-2, 2846, 2834-2 in a 2824-2 and 2892-A2 movement. But you can't go the other way.

2824-2 and 2892-A2 are flat date discs. The 2836-2 and 2846 are stepped for an overall thickness of around 0.6mm (approx), and the 2834-2 has a step for overall thickness of .40mm (approx)

fyi - 2834 discs are great for 2824 and 2892 franken projects

Thanks, all, for the responses and council. This would have been installing a 2824 wheel into a 2836 so I guess it's a no-go.

As stilty mentioned, the 2836-2 datewheel is stepped at the gear/teeth, whereas the 2824 and 2892 are flat. If you need a 2836 datewheel, I can check my spares for you. If I have one, of course it would be gratis to you

what would happen if a 2824 was installed? I believe I bought one off the bay a while back to replace one in my 2836 and it sits in the movement as we speak

[ubiquitous]

A 2824 datewheel just won't fit correctly; the gearing/teeth are stepped down to fit into the 2836's channel/ratchet. The flat datewheel for the 2824 lacks that step, and hence won't fit properly.

When I get home (and if there is enough daylight), I'll snap some pics to illustrate.

Some pics of the datewheels, as promised.

2836 has the stepped lip:

This next pic is not so great as the DoF is rather shallow. But it still gets the point across:

Hope this helps...
