I will confess to knowing nothing about your Bund, but it certainly is a beautiful watch in any case. :>)))

: First of all, I apologize for my poor english, I'll do my best to
: make that post as intelligible as possible :)
: I'm trying to get some clue concerning some partiularities of my
: watch

: I'm the proud owner of a nice exemplar of Heuer Bundeswehr 3H
: chronograph:

:

: Beyond its wonderfull condition, it displays the rare (unique?)
: feature of having short chronograph pusher and unstepped
: "pusher holes"

:

:

: Unlike classical Heuer Bunds (random pic from google :)

:
:

: Besides, the case do not display the usual 1550SG... engraving
: between the lugs, but they might have goten errased by a case
: polishing/microbeading.

:

: That kind of pushers/case reminds me strong of those from Sinn 156
: chronographs :

:

: Have you ever observed such characteristics on other Heuer Bund ?

: Have you an idea of the possible history of this Bund ? (very small
: production, service case and pushers from Sinn, based on the 156
: case adapted to Heuer Bund etc... ?)

: Thank's for helping me finding the in and outs of that beautiful
: piece of history :)
