… dear DrNo The watch you pictured is an Omega WWW CK2444 Below is the CK2777-1 Thin Arrow (along with a lovely CK2914 and a MoD dial Fat Arrow) (From internet)
Just in, a watch I was after for quite a long time, but never pulled the trigger for… well no logical reason Now I’m very pleased I did… except the need for a TA is more vivid than ever !
