TxRub779 1 Posted May 25, 2012 1601 Datejust *Genken (99% Gen/Franken) Build This is one way to build this franken datejust. Thanks to Wiz, KBH and jmb for the help with this build data. **special thanks to my friend and fellow FtWorth, Texas resident jmb for the build.

If you spot this engine turned bezel in the wild its most likely a 1601. Gen Acrylic Crystal for 1601 or 16000 (can use sapphire if wanted) as far as I could tell in my research the arylic crsytal was in use until the mid 90's, about the same time Rolex in general developed the saphire crystal for all models...the 1600, 16000 series both had acrylics and drilled lug cases untill mid or late 90's (edit if needed) I based this detail on the fact that I had a gen 16013 DJ, the quentisential DJ, tt jube bracelet, YG bezel/crown, chanpagne dial, drilled lugs, acrylic crystal, 3035 and a 1991 model serial. gen 6mm twin lock crown and tube ** (special info read) ETA 2824-2, after test fiting the 2824 in the gen 1601 case it fit almost perfect BUT jmb thought he was going to need a 2836-2's Date Disc w\that step up disc design to work properly. He ended up customizing a 2824 Date Disc buy grinding all the teeth off the inside of that date disc and gluing it to the bottom the the existing date disc to basically use as a spacer to lift the 2824-2's date wheel up high enough. This did put the 2824's stem at a slight downward angle, however there is *not enough stress on the stem to cause any problems other that having to find the sweet spot" to spin the crown into the tub to seat the crown tight...if you did anymore spacing than this, *jmb said you will need a taller cannon pinion and gears to work (prolly the same mods required if you use a PiePan dial as well) so its not a big deal for me, might be for some of you guys though so I mentioned 'it. DWO with appropriate vintage font mine had flat 3 open 6&9's (jmb custom DWO) *Oyster or Jubilee or rep bracelet.... the ELs will need to be tweaked to match the vintage case or you can source a gen bracelet but be prepared to spend $$$ ** * * * * * * * * ** The gen *1575 movement is 19,800bph, non quickset date version of the 1570....used in Rolex models for about 25 years as far as I can tell until the 3035 was introduced about 1978.... The Dial (Very Important) ** I used was a 16000 series dial, slate grey tapesty...the 1600 serie dials are called a PiePan and they have a very specific purpose and look , however for an ETA swap it really doesnt matter..however the PiePan will prolly take some movement mods like taller cannon pinion and gearing..the flat design of the gen 16000 series dial works perfect for my\our build. Pie Pan Non Quickset Dial Flat Quick Set Dial Specifcations on Genuine parts 1575 vs. 3035 dementions ** *The diameters are the same, but the heights of the 2 movements are different - 1570 - 5.75mm *No Date 1575-6.30mm Date* 3035 - 6.35mm Date Rolex Case - Case Size/Lug Width- Model - Dial Size - Notes **1600- 36mm/20mm - DateJust - 28mm - pie-pan dial non quick set **16000- 36mm/20mm - DateJust - 28mm -flat dial quick set **16200 Series * *36mm **The *1601 has a 1575 (not a 1570), which has a height of 6.30mm, so it may be an even swap. I have never done this, so I cannot guarantee you will not run into stem alignment issues or problems fitting the movement into the case.* Case and movement comparision (read close) http://www.rwg.cc/to...ith-a-3035-fit/ Member Posts (various fourm boards) I'd like to change the look of my 1601 and the range of available dials is greater with the later datejusts. Can the quickset dials like the 16xxx series be adapted to 1601's? Answer: ...dials, means cutting the feet off, and repositioning them. Not something I would advise. But people do it all the time. Answer: For one, the dial plate is of a different fitment size on a QS Datejust verses a 1601 non Quick set. Even if you reposition the dial feet, the case lip line up with the dial is off and the design depthness for the thicker 3035 movement only works for a QS dial. A gap will remain around the case inter rim.* Also one other big problem to add to the rest is, that the center hole on the QS Datejust dial is cut out is of a larger diameter in order to fit the thicker canon pinion which supports the minute, hour and second hands of the caliber. A 1601 dial has a smaller whole cut out in order to support the thinner 1570 cannon pinion.* 1601 Non QuickSet DIAL w/2824 ** Datejust Pie Pan Dial ** * Rolex *Oyster Perpetual DateJust ref# 1570 Diam. 27.3mm ** * http://forums.watchu...iex-629612.html ** *Pie Pan-"pie-pan" the definition is a dial that has the hour/minute markers placed in a concentric ring that slopes down at a constant angle (ie, not rounded) from a raised flat center, and that the center is often a contrasting color or tone and To me a pie pan dial 1) Has a crisp fold between the center and outer region 2) Has the minute marks inside the metal markers 3) Has straight edges, that is the inner part is a dodecagon. 4) Has the same shade and color on the inner and outer parts. When it comes to Datejust dials there are basically only two kinds of dials: quick-set and non-quick.1 **Remember, there is always a possibility for your watch to be vintage model 1601 and quick-set dial will not fit it in. Or your watch can be counterfeit – in this case out dial will be absolutely useless to you. Bracelet *Is the bezel smooth, or fluted? If smooth, it most likely had an Oyster bracelet. Jubilee with D links, USA made, and with the clasp/crown combo described above. Very vintage look What's likely "correct" though, would be the USA oval link (solid) or the swiss made oval link (not solid 1972 the folded link oyster bracelet is introduced In 1976 Rolex creates the Solid link, manufactured in just one piece. The last links had screws to take out and fasten the bracelet to the wrist.

The movement of choice, in the ETA line, for a 1601 case, would be the 2824-2. It is about .5mm(?) thinner than its counterpart. You can use a movement ring from rafflestime (see link below) and it will work perfectly. I have done it and the only modification to be made is on the ring where the case clamps cross it. It is too high and needs to be milled down just in those two spots. I used a Dreml tool with a cutoff wheel. Could be done with a file. http://stores.ebay.c...22&_sid=5404262 P. S. I believe that you need the #2 ring.* Although my build was a little different, I used a 1601 case to build an Explorer I, I did use a 2824-2, but I had a stilty ring which I used as a spacer. But everything went together smoothly. I also picked up a NOS 24-600-0 crown which fit the tube perfectly replica 1601 http://www.warwatche...79-watches.html 16000 Series **Men's Oyster Perpetual Date Just 36mm Plastic Crystal Quick Set It was manufactured approximately from 1977 until 1989 The characteristic for this model are the same as the previous model. The only difference would be the Quick Set function. It has a plastic crystal with 27 jewels, the case measures 36 x 12.3 mm and with holes on the sides of the lugs for the pins.

dalboy 2 Posted May 25, 2012 Your research, attention to detail and build are mind boggling.as someone who would not have the mindset to do this i still appreciate all the background research you have put into gathering all the nercassary component parts to complete the build. One very nice time piece you have there, along with the plearsure of completing it all yourself. Very impressive indeed Dal...............................

TxRub779 1 Posted May 25, 2012 I did NOT build this watch, jmb did so let me clarify that. jmb is a Jedi Master modder. I did however, do the due diligence, research and parts sourcing so all jmb had to do was his thing, build it. I am NOT the builder guy, I would end up breaking shit lol..I am capable of doing what I did, gather all the stuff to do it, that way I feel involved and its a very personal experiance for me.

Arism 26 Posted June 23, 2012 Nice one Rob. Was following this over on RWI. Just a quick question, do you know if Justin used a movement adapter to secure the movement in the 1601 case? I'm trying to figure out whether I need one to fit a ETA2472 into my 1601 case. Share this post Link to post Share on other sites

TxRub779 1 Posted June 24, 2012 Nice one Rob. Was following this over on RWI.Just a quick question, do you know if Justin used a movement adapter to secure the movement in the 1601 case? I'm trying to figure out whether I need one to fit a ETA2472 into my 1601 case. It was a 2824 ETA and yes he made 1 spacer/shim but I dont believe he needed a movement spacer in the normal sense... he used a 2824 date disc and ground the teeth off the one date disk and used it as a shim to shim the spacing of the existing DW (I believe thats correct) to align the ETA stem to the gens tube and crown and I am pretty sure the 2824 fit the gen 1601 almost perfect...but I may need to freshen my memory up on that.. When we mocked up the case, movement and dial..it was almost a perfect fit sans that one shim he needed to faricate Share this post Link to post Share on other sites
