What’s your Favourite Watch of all Time?

One is my old trusty Casio F-91W, I wore in the high school, university, army, wedding, first child birth. From the current:

Speedmaster was my dream watch for decades, I finally got one a month or so ago. Really new to me, but don't disappoint despite the very high expeectations.
Railmaster is my first Omega. It practically kicked out the other watches from my wrist since I have it.
With this Vostok we had some very special adventures, I count it among my current favs.
The Nomos Club was long time my daily watch. I don't consider Nomos watches anymore, but this piece is objectively a very good watch.

The 36mm Day-Date is watch perfection, in my opinion. Perfectly proportioned. Workhorse movement. Insanely comfortable.

or otherwise perhaps my Railmaster

Love the OG Railmaster. Will be part of my collection someday.

If I were to buy one more watch then stop all together, it would be a PP 5124G Gondolo, salmon dial
