Very nice.
Just wondering what the triangle marker at 1.30 for?
How do you operate it? Crown at 3?
The triangle marker is actually movable. It is lumed on the inside of the crystal and to move it, just grab the coin-rim bezel and turn. The bezel movement is silky smooth! Line it up with the minute hand, and you have a time elapsed marker. Line it up ahead of the minute hand (or even hour hand), and you have a countdown timer.
An excuse anyways to post more pictures as the "what is on your wrist today?" pic.


And the back, and see the beauty of the IWC hand-wind manufacture movement!

The strap is a beat worn and loose at the lugs,
you guys can recommend a good third-party strap maker for this?
22mm and the lugs, taper down to 18mm at the buckle. I'm trying to find a riveted strap like for the Big Pilot.
