I’ll have a go. Thinking carefully about the terminology, “favourite” - in my head, that means the ones worn most or have special meaning.
Omega Seamaster NTTD
Bought after selling up, lock stock and barrel and leaving the UK and setting up home in a country where I do not speak the language or have any family - but do have friends and of course my lifetime best friend and life companion, my loving wife. No regrets.
It can be worn on the beach, in the pool and with the Ti bracelet or NATO or I have a white Zulander for the summer - is versatile.
Patek 5146J
Bought from the last money from my mums estate - always a special place. Lovely watch, must dig out and wear it. Not sure if there is a rubber strap that would suit it?
Is the NATO blasphemy?
Patek 7234G
Most recent significant purchase. Maybe need a rubber 19mm strap to go with it - though the aviation OEM does suit it.
A close mention goes to my Dad’s Rolex Air-King-Date. I don’t wear it very much but will never sell it.
