Lemania 5100 movement family...

Yesterday I was contacted by Jorge Robles asking about 5100's, specifically asking if there was a family of chronograph movements based upon the Lemania 5100 movement such as 5012, 5195 and so on. He had seen a number of eBay auctions that mentioned these movements but had never seen anything written up describing them. Of course there is a family of movements based upon the 5100's. It's not as extensive of a family as the Valjoux 72 family I detailed previously, nor the Valjoux 7750 family of movements, but it has some unique members that deserve mention and catagorizing. I composed a reply to Jorge with a basic rundown of the 5100 movements I could off the top of my head, and CCed Pascal Straatsma... If there is anyone on this world who's a bigger fan of the 5100 than I am, it's Pascal. Pascal responded with a number of additional links and photo's... This post is a listing of 5100 movements. Ok, let's start out with the most commonally seen of the 5100's the Lemania 5100 itself... Base Lemania 5100 This is the standard conventional layout of the Lemania 5100. Manufacturers can elect to include Day or omit it as they see fit, and sometimes they do to allow room for their logo or other printing on the dial. -- Photo by Chuck Maddox Lemania 5012 The 5012 is a 5100 without the 24-hour subdial and also runs at 21,600bph as opposed to the 5100's 28,800bph... -- Photo by Chuck Maddox -- Photo by Pascal Straatsma However, a lack of a 24-Hour subdial does not automatically equate to a 5012 movement. Pascal owns another Lemania chronograph without the 24-hour Subdial but it has a 5100 under the dial: -- Photo by Pascal Straatsma Lemania 5195: The 5195 is a quasi-"Compax" subdial arrangement no-date version of the 5100: -- Photo ruthlessly stolen from an eBay auction for educational purposes... The 5195 variation might have significantly different "guts" than a 5100, don't know, I've never examined one personally, neither has Pascal. To our knowledge the only watch that has ever offered this movement has been the Eberhardt & Co. Frecce Tricolori model. Eberhardt also offered a Frecce Tricolori model utilizing the 5100 movement. Pascal owns an example and it's pictured below: -- Photo by Pascal Straatsma Incidentally, Frecce Tricolori is the name of Italy's acrobatic flight team... Lemania 5190: The 5190 is a model I know little about, however Pascal owns one, so I'll turn the narration over to him...: Just like the 5195, it does away with the day-date indication to have a classic tri-compax layout. But while the 5195 simply puts the usual 24 hour subdial at 3, the 5190 replaces it with a moonphase dial and a tide indicator. As far as I know, this movement was used by only one particular watch, the Eberhard Champion Maréoscope: -- Photo by Pascal Straatsma -- Photo by Pascal Straatsma -- Photo by Pascal Straatsma -- Photo by Pascal Straatsma Lemania 5200: The 5200, simply put is a "sans-rotor" manual wind version of the 5100. To both Pascal's and my knowledge only Pryngps offered a Lemania in this configuration...: -- Photo unapologetically stolen from an eBay auction for educational purposes... The old 5100 movement looks a little naked there without the rotor... It appears to keep the 2 banana-shaped nylon parts designed as a rotor rest. -- Photo unabashedly stolen from an eBay auction for educational purposes... I guess since they aren't any taller than other parts of the watch, there is no advantage in thiness by removing them, so I guess they leave them in. Weird!   Lemania 5250: Apparently there also is a Lemania 5250 movement... The only way we know about this is from two webpages supplied by Pascal: here in the "Handaufzugswerke" section, and here. Simply put is a "sans-rotor" manual wind version of the 5012 complete down to running at the slower 21,600 bph rate. Neither Pascal or I have seen an example either in person or on the web. If you see one, or own one, please contact me! To the best of both Pascal's and my knowledge this is a complete listing of the variations of the 5100 movement family. Of course and as always, if anyone has additions, corrections, refinements to my knowledge, please feel free to contact me with them. Special thanks to Pascal Straatma for his interest and efforts in the creation of this post!. -- Chuck
