Grail to me is something I don't have (yet). I'm currently obsessed with triple date moonphase. This 2471 from Omega Enthusiast is my grail. Unfortunately it's not for sale. The search continues...
Just take your time - nice examples pop up once in a while. After u dig deeper in the tdmp u can also easily identify redials - which make a ridiculous high %age of the watches offered.
But be aware good examples have a strong competition as some people really hunt for them - e.g.
@cristos71
I also got hooked by the Omega tdmps a few years ago.
They have been my grail watches and still are and I am lucky having found some nice examples which come very close to a real grail watch - they are not in perfect condition and that's why not real grail watch. Anyhow as they are not in perfect condition I am happy to wear.
If it would be a NOS I would avoid to wear because of danger to receive any small scratch or dent - so I feel like I have more enjoyment with a not NOS watch... Here are some pictures of my favorite examples:
But I assume you all know how it goes with watches...
So many things to explore and lately got hooked with the (omega) 33.3 caliber and in general watches with that style with more than 35mm diameter from the 30s/40s.
One grail to be mentioned here is the Omega multiscale ck2077 in waterproof case (with round pushers) and 38mm diameter - actually for sale in Zurich for a very high price :

I just like how perfect the dial, the scales, the colour, the case and pushers add up. Just looks like a perfect composition of watch making.
For sure the Omega above or with another dial variation with a waterproof case will be a "dream" grail watch.
