A Cosmonaut here as well, on a Mobylot bracelet. I did an Akrotiri trip from Luqa and was asked to pick up and pay for a pair of headlights for a Triumph 2.5pi for one of our groundcrew [M.E.Quick - his name is on the paperwork and box}(the headlights were about £25 ) and while I was away he had wrecked a Maltese wall and his car as well. He gave me his Breitling as a payment and though I offered to swap again later, he said no.
I still have it and just had a major service for £300 including just about everything visible.
The Mobylot bracelet (stainless fine mesh) still mystifies me, but two unconnected jewellers say Mobylot is a bracelet of choice. The original is still new in the box 45 years later.
