My IWC perpetual calendar chronograph is now a teenager, and although many IWCs have come and gone through the watch cabinet, he's never had a friend. But thanks to my generous wife, an article by Nilomis, and a chance sighting, I got a new watch for Christmas!
Yes, it's the split-second chrono; rattrapante or whatever you call it - the matching watch!

I know this a dial only a nerdy engineer could love - but beauty is in details, right?

Look at the second hands - hollow arrowhead tips! They match up perfectly when not split. A perfect gift in my stocking!
