...on hunting the 5402. There have been some threads here in the past related to such searches for this iconic watch, so perhaps do a search here and on the sister Network54 site.
I don't blame you for being cautious about hunting a 5402. I have held off myself because it is a minefield and it will be challening to find a near perfect and all-original example accompanied by full provenance. But most collectors are transfixed by the logo above the 6 o'clock. For now, enjoy the stealthy nature of the 15002. ;-)
And you and I both need to get over the idea of keeping our 15002s in mint condition. That is one of the reasons I thought about getting a 15202 or even a 15300. Each of these watches is meant to be worn, however, right? I am wearing mine today, in fact.
Enjoy!
