twinfake Posted January 28, 2009 Report Posted January 28, 2009 Did a search did not find quite what I wanted so. On datejust what years did they have lug holes, or what years would they be solid?. Up to when would a slow beat movement be used on a dj?. I don't know so much about rolexs so please forgive me lack of knowledge. Just want to build a better rep from one I already have.
alligoat Posted January 28, 2009 Report Posted January 28, 2009 I'm not sure when the lugholes went away- somewhere into the 16200 models which are the ones with the latest movement- the 3135. Maybe around 2000... The slowbeat 1560 and 1570 movements in the 1600/1601 DJ's were around until the late 70's, replaced by the 3035 movement and the 160xx models around 1978-9. The 1530 and 1560 were the early slowbeats- maybe 18000bph-used up into the middle 60's The 1570 and 1520 were 19800bph- if I'm correct and replaced the 1530/60!
freddy333 Posted January 28, 2009 Report Posted January 28, 2009 Slow beats ended with the (19.8kbph) 1575-powered 160x series in the 70s. Lug holes are harder to pin down (no pun intended), but I am pretty sure they vanished with the appearance of the (28.8kbph) 3135-powered 11601x series in the 90s. Mid-80s 3035-powered 16014 on the left & 1970 1575-powered 1601 on the right (both have lug holes)
Toadtorrent Posted January 28, 2009 Report Posted January 28, 2009 Feel honoured, Twinfake!!! You just got some outstanding answers from 2 Rollie masters!!
alligoat Posted January 28, 2009 Report Posted January 28, 2009 One thing, Freddy, the slow beat 1520 was around into the late 80's in the 5513. Finally replaced by the 14060 w/ the 3130 movt around 1990, give or take a year. Amazing that it lasted so long in production.
freddy333 Posted January 28, 2009 Report Posted January 28, 2009 Yes, but I think his question was limited to the DJ.
alligoat Posted January 28, 2009 Report Posted January 28, 2009 OK. It is interesting how the Datejust was kinda at the forefront of Rolex movement development. 1565, 1575, 3035 and 3135. Of course, it's been around for a long time.
freddy333 Posted January 28, 2009 Report Posted January 28, 2009 Traditionally, I think Rolex tends to throw the newest technology into their most popular models.
twinfake Posted January 28, 2009 Author Report Posted January 28, 2009 Wow thank you for the replys. Very interesting, ok so a dj without lug holes should have a fast beat movement, just on a rep I have (will post pics tomorrow) has no lug holes but has a slow beat eta (gen) 2846.
alligoat Posted January 28, 2009 Report Posted January 28, 2009 A 2846 is 21600bph. Sure it's not a 28.8K beat, but people really can't tell the difference just looking at the second hand. But if you were able to trade for a 2836, it would at least have the correct beat. But it's not that big a deal IMO.
