The Lemania 5100 Family of Chronographs...
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...
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

and also runs at 21,600bph as opposed to the 5100's
28,800bph... -- Photo by Chuck

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

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

Italy's acrobatic flight team...
Of course and as always, if anyone has additions, corrections, refinements to my knowledge, please feel free to contact me with them.
