JLC today, still working on toning down the strap, almost there ?
As it arrived,
Today,
Looking far better now, I've considered one of these in the past but did not like the look. Yours has aged perfectly so better reconsider. Have you used a speed up trick and where do you buy them again as I've long forgotten?
[Edit]just seen your further reply which answers the first question.
Omega 6b/542 58 issue bought in the 1980's by the previous owner at an RNZAF military surplus auction. The dial and hands were possibly changed by the RNZAF. Dial is the thick anti magnetic type.
