Move a bnib 116600 for a PM sub?

[Kestrel]

I always thought of myself as a SS guy. A black dial 116660 is my daily on a 7 5/8 (19.3cm) wrist. Was looking at a white dial 216570 or iwc big pilot as my next piece. Thanks to TRF, the 116613lb caught my eye, despite my aversion to TT. But that got me thinking about a pm sub. 116619 has always been a grail of mine but I saw a 116618lb at my AD recently and that reference is pure magic. Not sure I could pull of YG, though...the ‘619 is more my style.

At the moment, I can’t make the jump to PM without trading my BNIB 116600. I bought it in 2016 but held to see if a new 50th reference would come out in 2017. It did, and then I wasn’t sure what to do so I held tight. The 116600 is basically perfect, but I just could never bring myself to pull the stickers off especially when I love my 116660 and the are similar if not similar wearing.

So what is the best strategy here? Move to PM and don’t look back or keep on the SS path? I know I’ll get a white dial 216570 eventually.
