I tried the 105.003 with a leather strap, but it seems like i never get hold onto it for a longer time.
So i decided to swap the 1039 from my 145.022 71 ( which was in fact procuded in 1975 and delivered
with a 1039 according to the extract of record) and the 145.022 got a 1168 with punched 633 endlinks
which is also periodically correct, isnt it?
