vlydog Posted March 6, 2008 Report Share Posted March 6, 2008 I plan on swapping out the MBW movement in my 1665 for a slow beat movement. I purchased a new ETA 2846 but it has a noisy rotor. Are there any other movements that would be at home in this vintage sub? Thanks. Link to comment Share on other sites More sharing options...
tmg Posted March 6, 2008 Report Share Posted March 6, 2008 Maybe 27xx series ETA's but those are harder to source. Link to comment Share on other sites More sharing options...
vlydog Posted March 6, 2008 Author Report Share Posted March 6, 2008 Maybe 27xx series ETA's but those are harder to source. Thanks tmg. The reason I ask is that the 2846 I bought has much rotor noise. I not sure a little grease will be the solution. Link to comment Share on other sites More sharing options...
Stephane Posted March 6, 2008 Report Share Posted March 6, 2008 Hi All, I was lucky enough to get JustAsGood's 5513 that feature a slow beat eta (not sure I remember which one though). It is indeed a nice difference for a vintage Rolie to see it beat slowly. I still have 3 vintage SDs hosting 2836 @ 28800... I would love to see some of our usual specialists chime in and teach us which one should be sourced. Cheers Stephane Link to comment Share on other sites More sharing options...
Guest avitt Posted March 6, 2008 Report Share Posted March 6, 2008 Is your 2846 new or used? Has it been serviced recently? I don't think that rotor noise is inherent in the design of that movement...Mine's pretty quiet. Link to comment Share on other sites More sharing options...
RWG Technical Posted March 6, 2008 Report Share Posted March 6, 2008 Maybe 27xx series ETA's but those are harder to source. I have at least 2 ETA 2789's (not certain on the exact caliber) in my spares bins...gathering dust...didn't know they were hard to find... 2846's are easy to find, but due to the vintage, probably need to be serviced. As avitt pointed out, the 2846 is normally virtually silent when the rotor turns... RG Link to comment Share on other sites More sharing options...
vlydog Posted March 6, 2008 Author Report Share Posted March 6, 2008 @ ziggy Are the ETA 2789's a suitable alternative to the 2846? If so, I would be interested. Link to comment Share on other sites More sharing options...

I am not 100% sure, they are the same size, and I am assuming the hands etc are the same as the 2836, 2846 etc... I'll have to check. RG Link to comment Share on other sites More sharing options...

You I'm sure know better than me Vyldog, my 2846 is also very quiet in my 1665. Link to comment Share on other sites More sharing options...

I am certain that it is not serviced. Link to comment Share on other sites More sharing options...

RWG Technical Posted March 7, 2008 Report Share Posted March 7, 2008 I checked my spares, I have 2 ETA 2781's in stock, working but in need of servicing due to not knowing when they were last serviced. The hands are the same size as the 2836, and it appears to be dimensionally the same size as well, so I would guess that these can also be used instead of a 2846...

Stephane Posted March 7, 2008 Report Share Posted March 7, 2008 Interresting inputs guys. Vlydog, yours must have a rotor issue So whatever ETA ref, it is fine as long as the hands fit the mvt and the size of the mvt fits the case. Another question about 2846s: what are their true value in terms of money? Could anybody tell us this? Thanks & Cheers Stephane Link to comment Share on other sites More sharing options...
Stephane Posted March 7, 2008 Report Share Posted March 7, 2008 Hi Robi, Thank you so much for your help. 80$ shiped seems a good price indeed Cheers Stephane Link to comment Share on other sites More sharing options...
