ubiquitous Posted March 14, 2006 Report Posted March 14, 2006 The title says it all. I downshifted the beat of my MBW to a frequency closer to that of a vintage 1570. Some videos to capture the sweep seconds; (3.5M) And one to compare against a 28.800bph ETA 2836-2: (4.6M) (click the images for the videos) The new movement is 100% Swiss. More info to come soon; I want to monitor long term performance a bit before revealing further details on the type of movement used. Cheers, Randy
XRT Posted March 15, 2006 Report Posted March 15, 2006 Do tell...what is the movement and how has it been working?
archibald Posted March 19, 2006 Report Posted March 19, 2006 (edited) I want to monitor long term performance a bit before revealing further details on the type of movement used. We don't want anyone to get hurt.....I remember my watchmaker telling me what kind of movement lots of folks use on the old rolexes once in one of his rants about vintage rolex reps (he's passionate about genuine vintage rollies but is still pretty rep friendly). A.S. I think...I'll check. Edited March 19, 2006 by archibald
TomBombadil Posted March 19, 2006 Report Posted March 19, 2006 Great idea. Its funny how looking at some watches, you can tell that the sweep is too smooth and just doesn't look right.
ubiquitous Posted March 19, 2006 Author Report Posted March 19, 2006 I've been watching and monitoring performance now for about a month, and the new movement has been running like clockwork (pun intended). The time keeping has been a little fast, but within the past week or so seems to be slowing up a bit to become a little more consistent. I haven't really played with dial up/down/left/right positions overnight to try to correct time gain/loss, but I'm sure with some experimenting, I could get the correction needed for even better time keeping. Anyhow... Before I move on to the specifics of the details, anyone care to take a guess as to what kind of movement is taking up residence in my MBW? Here are a few pics to give you guys some clues.
Bazz Posted March 19, 2006 Report Posted March 19, 2006 (edited) ETA 2846? Edited March 19, 2006 by Bazz
ubiquitous Posted March 19, 2006 Author Report Posted March 19, 2006 Very good eyes, bazz! It is indeed a 2846! And, it's a perfect fit as it's physically identical to a 2836-2; 11.5L x 5.05, 90/150/25 hand stack, and it even uses the same stem. Beat is 21600bph (6 ticks per second, vs. the 5.5 ticks per second for 19800), and the movement is non-hacking. This one worked so well that I picked up two more for some other projects
slickdick Posted March 19, 2006 Report Posted March 19, 2006 (edited) Nice work!, the 2846 is good alternative indeed and an easy swap. Edited March 19, 2006 by slickdick
slickdick Posted March 19, 2006 Report Posted March 19, 2006 btw, how does the 284x series advances the date CW o CCW?
ubiquitous Posted March 19, 2006 Author Report Posted March 19, 2006 Date advances clockwise, as with the 2836-2. Ultimately, the 2846 currently installed may not be the movement I end up using. I have some different movements en route to me that may prove to be the better solution. But for an easy, drop in solution, the 2846 works a charm.
HauteHippie Posted September 17, 2006 Report Posted September 17, 2006 So Ubi, are you still using the 2846 or did you find a better alternative?
ubiquitous Posted September 17, 2006 Author Report Posted September 17, 2006 Still using the 2846! Runs perfect with a nice staggered beat! I love it! All that's needed on it is the new datewheel (which we're working on) and it'll be complete...

Linder Posted September 17, 2006 Report Posted September 17, 2006 Ubi, you need to make some money off these datewheels. I know I would certainly like to buy one
ubiquitous Posted September 17, 2006 Author Report Posted September 17, 2006 Once they are perfected... Absolutely!
Justasgood Posted September 17, 2006 Report Posted September 17, 2006 Well I guess I must have done something right....I transplanted the exact same movement (Tissot Rotor and all) into my 5517. I love the lazy beat rate and it comes real close to my gen 5513 . UBI UB DAMAN! I always enjoy tour posts and mods.
ubiquitous Posted September 17, 2006 Author Report Posted September 17, 2006 Oooh! Good stuff! You can take your 5517 a step further with some Yao MOD sword hands... A bit better in shape and size for the Mili
Justasgood Posted September 17, 2006 Report Posted September 17, 2006 Oooh! Good stuff! You can take your 5517 a step further with some Yao MOD sword hands... A bit better in shape and size for the Mili Serious? Are they closer in size to the gen? What about thecolor variation? Since I knocked out the pins and now have Gen springbars, I was thinking of just modding the CG's and converting this sub into a 5512 or 5513. Thoughts....
cib0rgman Posted September 17, 2006 Report Posted September 17, 2006 (edited) Always looking for Perfection, Nice Job UBI. Does anybody know is Ofrei have this movements for sale. thanks Edited September 17, 2006 by cib0rgman

Hour and min hand are much nicer, wider, and better shape. Seconds hand, however is still slightly wrong. However, modding this to a 5512 would be rather interesting as well! Throw on a nice T-19, insert, dial and hands, and you're set Always looking for Perfection, Nice Job UBI. Does anybody know is Ofrei have this movements for sale. thanks The pursuit of perfection... Or as close to as possible... It's what keeps me going You may want to check around with Frei, Borel, etc. awsome ! now thats theral work !! you da man UBI As always, thanks Big E!!

beever Posted September 9, 2007 Report Posted September 9, 2007 I was wondering if you guys know of anyone, either a member, vendor, watchmaker (YOU) etc.. who has modified a double red or seadweller or any of the vintage rolex sport watches to look nearly indistinguishable and would like to sell it. The rivoted bracelet is awesome and the mods made make some of these replicas look suburb. Maybe you guys know where I can get my hands on a replica that has been heavily modified to look genuine. If you can help me out it would be much appreciated. Most of the articles i have red claim that no vendors have them looking "right" but after modification they are pretty spot on so, if someone is tired of their modded Rolex or knows of someone who wants to get paid for a project, feel free to PM or reply.
