Can't believe it's been four years since we had the very first Perpetual event:

home.watchprosite.com

Nevertheless, we've still managed to gather a few new acquisitions to be shared on this special day:

Like the owner, this Annual Calendar CAN'T wait to finish ahead of everyone else that by 23:05, the date already ticked over to 1st March. The transition did complete the week day move toward midnight although I can't seem to find the picture for that...

The Big Pilot Perpetual Z&C did start around 22:53

and finishes shortly after midnight

The Dato Perpetual started around 22:45

and finishes around 00:42

The PP, like it's peer, start late around 23:22, unofrutnately we didn't stick around long enough to watch the finishing line!

I tried quite a few times to capture that 'flash' but it's just not possible...

The double hairspring!

Here's another instantaneous one that's impossible to capture. Fortunately I had it on video so I'll be posting the transition in due time!

The RD starts also around 22:41

And finishes shortly after midnight, although I realized that the weekday transition hasn't quite finished yet!

Another late starter

I have a very blurry picture which documents that the this beautiful skeleton piece finishes the transition around 02:45 in the morning...

Bravo to Eric for the wonderful arrangement of the venue.

Your post just enforce my desire for the Moser P1, fume dial of course. Interesting observation on the IWC BB. These instantaneous are really my cup of tea. You know any others? Regards Tyler

Wow! You guys had great watches to watch. We (in LA) were more occupied with talking, drinking, eating and carousing ... Cazalea
