jmb Posted April 14, 2015 Report Share Posted April 14, 2015 No... The datasheet I have lists 4 different lengths... Link to comment Share on other sites More sharing options...
Dlf Posted April 15, 2015 Author Report Share Posted April 15, 2015 Do you think this is broken or just an awkward correct version ? Link to comment Share on other sites More sharing options...
jmb Posted April 15, 2015 Report Share Posted April 15, 2015 Kinda hard to tell from your fuzzy pic but the end looks rounded so it was probably that way on purpose. Some sweep hands have long "tubes" so can use a short pin like that. Link to comment Share on other sites More sharing options...

508-Fanatic Posted April 15, 2015 Report Share Posted April 15, 2015 Doesn't TC have a great article on pinion height? I think the said an H4 from O-Frei works the best for Rolex stack Link to comment Share on other sites More sharing options...
jmb Posted April 15, 2015 Report Share Posted April 15, 2015 Normally the cannon pin and 4th wheel need to be higher if the dial has the really tall markers like the vintage stick DJ dials but on others, like Roman markers, the standard works fine.

blue. Posted April 15, 2015 Report Share Posted April 15, 2015 I would say on an ETA, for dials with dates and as JMB mentioned, dials with high stick markers best cannon pinion would be H4. On builds with no date dials, best cannon pinion height is the H3. H2 height is an absolute compromise, would work but aint correct. The two occasions (H4 & H3) give a gen spec distance from the dial. Link to comment Share on other sites More sharing options...
sneed12 Posted April 15, 2015 Report Share Posted April 15, 2015 (edited) Are all eta 2846's like this with a recessed pinion? Impossible to install seconds hand without touching the minute. As others have pointed out, there are a number of different factory configurations. It's only "recessed" if you install a tall hour wheel and cannon pinion. There are 2836s with this configuration as well, not all (or even most) 2836s are H4s. Edited April 15, 2015 by sneed12 Link to comment Share on other sites More sharing options...
kbh Posted April 15, 2015 Report Share Posted April 15, 2015 From the second picture I'd say it's definitely broken. Anyway, to be usable you're going to need to replace it. Link to comment Share on other sites More sharing options...
Dlf Posted April 15, 2015 Author Report Share Posted April 15, 2015 The eta 2836 is stock and the 2846 hw and seconds wheel are same height, so I thinks it's broke as kbh said . Thanks for the help and suggestions guys Link to comment Share on other sites More sharing options...
