    Default Lorenz Divers' Registry

    In celebration of Andy's recent acquisition (or maybe because it finally reminded me to do this), I propose sharing details of our Lorenz divers' watches with the L5100.

    Why? Because there is not much information about when which watches were produced when. It would be nice to compare movement and model numbers to see if we can get a sense of how these watches fit into Lorenz and Lemania history.

    I volunteer mine as an opener:

    Number on caseback (model number?): 12042
    Movement: 04095631

    Good idea

    Here's mine.



    Caseback number 12042 (that's a match).

    Movement number 04030863.

    The movement serial is the early type printed into a medallion (not engraved onto the movement, as was done later).

    There are two service dates written inside the caseback - VD - 11/03 and MH - 09/98

    My 5100 movement number dates would indicate that this is from the late 80s, a slight possibility of early 90s. It is the earliest serial number I have, only a couple of thousand away from the Lederer chronograph I used to own which was a clone of the Heuer 510.501, produced 1980 onwards. To my reckoning, the 510 series clones made for Lederer and Tourneau will have been made in the last days of Heuer, and not during the tenure of Tag, so the end date for production would be 1987.

    The movement serial being such a close match would date the Lorenz from that period, but as ever, I am totally open to further information.

    My cushion-case Heuer Carrera carries movement number 04031848 and it was definitely made in the early 1980's, giving much credence to Dave's hypothesis.

    The question in my mind is when Lorenz put these watches together. The movements could have sat in the workshop for any amount of time. I know Andy's watch came with a box and some sort of papers: I wonder if they belong to the watch. It will be interesting to see what he gets.

    BTW I took a look: My Lemania-branded watch with Sinn 142 case carries a 5012 with serial number 04001473.

    There were clearly a few iterations of this watch, so my theory is that they were built over a considerably long period, with dial redesign / reprints going on a few times.

    The variations spotted so far (please feel free to add to these)

    Chrono-second hand being delta (or triangular) or winged dart. The latter seems o be later.

    Bezel staring with single minutes to 20, and a lume triangle. Subsequently moving to single minutes to 15, with a lume pearl.

    Dial script

    Mine just has:
    Logo
    Lorenz


    Daniel's
    Logo
    Lorenz

    Automatic

    Sub Professional
    200 Meters


    Brandizzi

    Logo
    Lorenz
    Automatic
    Sub Professional
    200 Meters


    However, it has not got the double spacing that Daniel's has. Pascal's is the same as the Brandizzi model.

    Andy's New one (and Chuck's)

    Logo
    Lorenz
    Automatic


    So, that is 4 different script variations before we consider that there are at least three dial type, all black, all blue, and black with silver sub-dials.

    Chapter ring - Tachymetre ring variations. Daniel's seems to be the stripped out one, that lacks the tachymetre. I have to say I like the simplicity.

    Pascal's tachymetre differs from mine, most notably near 6 and 8 where Pascals has lines to delineate each individual number between 120 and 90 on the tachy scale. Mine only has delineations for the 5s. Andy's and Chuck's share the design with mine.

    The signed bracelets also differ. there are ones with a gold (coloured at least) Lorenz medallion on the clasp, and some (like Daniel's) are plain steel. I also note that the centre of the three links on Daniel's is narrower that the one on Chuck's and Andy's new one.

    All in all that is a considerable breadth of variation for one model, and this indicates (to me) long production and many iterations of re-manufacturing.

    Here's the info about my example:



    Caseback reference number: 12042

    Movement number: 04395919 (engraved on the movement)

    Dial script:
    LORENZ
    AUTOMATIC
    SUB PROFESSIONAL
    200 METERS


    Chapter ring: Tachy chapter ring

    Crown: Signed "LORENZ", no logo

    Hi Pascal, thanks for adding your details.
    And the new variation - mine has a totally unsigned crown that I am fairly sure is original.
    Yours looks unsigned Daniel, is it?

    Also, in terms of numbers yours is significantly (300,000) later than Daniel's. The middle area of these numbers is a blank in my (rather small) database, mine leap from 403***** straight to 44******, so I am of little help pinning down dates in the 90s.

    Ouf!

    Just when I thought this might simplify things, it gets more complicated!

    Crown: Yes, mine is unsigned.
    Chapter ring: None. Mine has a polished spacer inside.
    Bracelet: 20mm at lugs tapering down to 16mm with embossed logo on clasp, which includes a diver's extension



    The center links on my bracelet measure 5mm wide if anyone is interested.

    My movement's serial number is on a round medallion like most (all?) early L5100's:



    Let's see if this number stamped inside the caseback matches the others:



    Funny thing: I wore my Lorenz today. Every morning I look for something to match my outfit and which I feel comfortable with. For some reason, the Lorenz gets the nod more often than many other pieces. I have to deliberately not wear it frequently.

    Do I like mine? Hmm, have to think about it...

    Just a quick one just now, will get some better pics and more detail when I get a minute!

    Soooo, a later one;

    Bezel marker - pearl lume

    Minute Chrono hand - winged

    Tachy - delineations for 5

    Crown - Lorenz logo

    Bezel - minute intervals to 15 mins.

    Dial -

    Logo
    Lorenz
    Automatic

    Finish - Brushed bracelet, brushed top of case, polished sides of case and polished sides to bracelet.

    Number on case rear - 16856 (product code)

    Lovely, great condition, certainly only worn a few times. paperwork relates to the watch being originally sold in April 2007 in Rome.

    As a bonus I've got the original wood effect box/cushion/outer box, plus the instructions/guarentee booklets.

    As I say, when I get chance I'll add some better pics, but for now it's happily being worn - I'm delighted!

    Wonderful!

    Once again, the small differences between these watches amaze!

    Just to update with a few more pictures out of interest.

    Mine has some slight corroding (I think) to the subdials, makes them ever so slightly reddish -



    Very lucky with the almost new condition of this one otherwise -











    Center links are 9mm btw way Daniel.

    And the 'backside'; notice the gold infilled logo on the bracelet, the caseback inscription and the 'top hat' crystal profile -




    (It's '20 ATM')



    Andy
