This one, in a full 18 karat gold case, belonged to my grandfather, I inherited it back in about 1973. It sat in a safety deposit box here in Montreal for about 25 years. In 2003 I went to work for a division of Swatch Group in Switzerland at which point I brought it to the original Gubelin shop in Lucerne for a complete refurb. They replaced the crystal, dial and hands (still had original parts!) but unfortunately I was too naive/uninformed at the time to request a return of those parts to me...I got the replaced mainspring and a few other bits, but no dial or other nostalgic/original parts. Aside from their potential original value, the original dial also said "Lucerne" under the Gubelin brand, which is how I found them to begin with. This new dial lacks the city ID as there are Gubelin shops all over the country now. Oh well, lesson learned. At least I now have an as-new 75 year old watch!
