The benefit is to have a 65 days power reserve

In simplified terms: while a high frequency gives you high precision, it will reduce your power reserve. Normally what watchmakers do is they find a compromise at the sweet spot of precision they need vs. PR they want.

With the Twin Beat, VC chose a different approach: they introduced 2 balances, one at 5 Hz for "active use" and one at 1.2 Hz for "standby mode". At 5 Hz, the watch runs within a few secs per day. When you don't wear it, you put it into standby mode and put it in the box. Here, the PR will last for 65 days. Losing precision at 1.2 Hz, you will need to adjust the time by a few minutes or hours when you take it up after 2 months, but you will not need to reset the calendar.

All in all, a novel approach to keep a perpetual calendar accurate. Most others go for an automatic movement and put it on a winder when not in use.

It spent the last 4 or so months in Geneva for adjustment. The downside of the 65 days power reserve is that QC takes forever ๐Ÿ˜„ Very happy to have it back on my wrist today! Happy 1. August to all fellow Swiss, and a relaxed Monday to everyone else. Danie...  

I do my best :-)

Iโ€˜m just noticing your new profile pic. Itโ€™s the Bocadasse, right? Quite remarkable too, in a very different way.

Ahhh.. perfection!

Yes. And I love how they reflect this in the design.

Still keeping the exceptional VC attention to detail in their execution.

Agree. Enjoy it !
