2pac Posted August 6, 2018 Report Share Posted August 6, 2018 Hi guys, I'm reading and reading..But I have a question for who have more experience than me.. The rolex 1665 drsd use a 1575 rolex caliber who is 28.5mm diameter and 6.30mm Thickness... The rolex caliber 3135 is 28.30 and 6.00 thickness.. My question is the following : the Sh 3135 movment Can fit in a 1665 Vietnam case? Thanks Link to comment Share on other sites More sharing options...
automatico Posted August 6, 2018 Report Share Posted August 6, 2018 On genuine watches a cal 3135 will not work in a case made for a cal 1570/5 date movement because the stem will not line up in the case tube. A 3035 will fit, depending on dial size. The beat rate is also wrong with the 3035 and 3135, both running at 28800 bph and a 1570/5 at 19800 bph. Cal 1530/1560 run at 18000 bph but they were not used in 1665 watches. The beat rate is really not important except it is a 'tell' because the second hand travel is much smoother on faster beat movements. 1 Link to comment Share on other sites More sharing options...

Perfect, I have to change project.I suggested this way for the dwo, nowadays there aren't good open 6&9 Link to comment Share on other sites More sharing options...
Ephry73 Posted August 10, 2018 Report Share Posted August 10, 2018 I would suggest a properly serviced 2892 movement with a decent dwo. Will run like a champ and be closer to gen beat and size wise. Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
