    Dear All,

    since I'm a proud owner of an Aquatimer ref. 371928 I plan to extend my small
    IWC collection with other pre-loved GST (by Marcus Eilinger) design
    chronograph watches and need some information about them. If any of you own
    one or more from the following watches and you'll have some free time for my
    questions I'd be happy to read some information about these watches - some can
    be measured, others are just your opinion and knowledge.

    So the questions are as follows (sorry, there are a quite a few of them...):

    3756, 3715, 378201, 378203, 3707 (and 371903) data needed:

    1. exact sizes (surely differing from official factory data!): height incl.
    crystal, diameter of bezel and of case middle part, weight on bracelet (if
    possible both steel and titanium versions) sized to fit cca. 6.7"=17 cm wrist)
    Weight of 371903 Titanium similarly sized?
    2. Are steel bracelets and rubber straps of ref. 3715, 3756 and 3782
    technically interchangeable? (I know, bracelet middle parts of 3782 is brushed
    while 3715 and 3756 polished but that's only the looks...) What is the all-
    brushed reference number of the steel bracelet for the 3782?
    3. End pieces of Velcro strap in steel ever made for 3782? (Titanium
    available for the 3756, coming from Deep One.) (I'd love to wear the 3782 on
    the Velcro but I'm afraid the end pieces were only made in Titanium, and that
    for the Deep One. Otherwise only steel bracelet or rubber strap to choose
    from.) If there were those steel end pieces made for Velcro, what is the ref.
    number?
    4. Width of the narrow part of the 3782 rubber strap and steel bracelet (at
    the buckle/clasp): 18 mm or wider?

    If you happen to know some GST/GST-AT collectors in my city Budapest I'd be
    happy to be connected with them so as to see their watches in the flesh
    (excluding the 371928 that I have).

    The reply is not urgent of course, just when you happen to baby your watches
    and have a sliding caliper and a kitchen scale at hand... thank you in advance
    for you kindness - I promise not to ask more questions in this quantity
    :).

    This post sent as PM to a few owners with knowledge too, but I'll be happy to
    read anyone else chiming in.

    Best regards from beautiful Budapest,

    Robert

    Hi Robert

    Nice chatting this afternoon, I'm working on some answers for you. My
    daughter's 3707 is at service at the moment. I will have it back soon.
