ThinkBachs Posted March 18, 2009 Report Share Posted March 18, 2009 On this new HBB, I've noticed that the second hand isn't perfectly smooth all the way around, especially at about the 55 mark when the seconds chrono moves to its next position. That part seems to make sense to me but I'll let the pros tell me for sure. Here's the watch... Here's a better video showing how it runs...

Rolexman Posted March 18, 2009 Report Share Posted March 18, 2009 Looks okay to me! Because the chrono second hand is longer than the second hand the 'jerkyness' motion is enhanced. It should show 8 fast tick per second. It could also very well be that there is some durt and dibree between the gears. You could have it serviced or let it run for some days to let it settle in (if the watch is new) ..... Remember, even gens sometimes have jerky second hands. Like the Chopard GTXL, Oh man.....

azerbyjam Posted March 18, 2009 Report Share Posted March 18, 2009 Looks OK to me too, but I think the minute register moving on 3 seconds before the chrono hand reaches 12 would bug me more.

See Francisco's excellent tutorial on how to fix this HERE Thank both of you very much. I like this statement in his tutorial... "The disassembling has finished, no difficult." Looks like it time to look into some tools! Quote Link to comment Share on other sites More sharing options...

Looks like it time to look into some tools! The only problem I see is getting the ETA part. I ordered day and date wheels from cousins one week ago, and still the parts haven't been dispatched. I contacted them and was told that many ETA parts are out of stock. Quote Link to comment Share on other sites More sharing options...
F1FAN Posted March 18, 2009 Report Share Posted March 18, 2009 Great looking watch! It's on my list. My SS/C YC does not jump at any point in it's movement. Quote Link to comment Share on other sites More sharing options...
