The beautiful and oft-overlooked Frederique Constant Slimline Moonphase. Incredible bang for the buck (if you buy right).
Nowhere close to the standard of Mick or Lou, but I love blue dialled watches (and hence I love this thread) so here is my small contribution until the SM120 "big blue" returns from service.
update from almost 2 years ago. Sold most of the non-Omega watches. Gave the Seiko to my oldest son. Still have the JLC.
