I bought my first chronograph from Exchange & Mart whenI was a abouts 20...it was called a Global and I had never seen a chronograph before...I don't remember owning a watch before that. I have worked in labs most of my working life and have had a a few chronographs. I live inEngland and am 74 years old. I have 7 watches but do sell off ones some time especially to get others I have always aspired to have a Breitling Navitimer since I was 23 but still have not got one. I qualified in Metallurgy a Chemistry but worked in associated fields for the latter part of my working life I have had or do have : Breitling (sprint) Seiko; Brathwaite; Christopher Ward; Davosa GMT; several Tissot, plus less known quirky watches
