I being a big fan of vintage Pilot watches, recently purchased a vintage(styled/ looking) pilot from Athaya Vintage…It uses a modern Miyota movement. I expect it within the next week… I've built a few, but this will be my first Pilot watch I've purchased with a center seconds hand.

I received the watch today(a pleasant surprise/ express shipping.) It looked great out of the box… The only issue, if you can call it that, was that the strap as it was, fit a little tight on my wrist in the last available hole… My choices were to change it for another, maybe a leather NATO, or pull out my leather hole puncher to add a hole or two. I did the latter which will allow me to wear it a little further up my wrist. This will keep the crown from rubbing the back of my hand. Besides that problem which I fixed in five minutes, it feels and looks very solid.

Indeed, I wore it on a different strap today. A nice soft oversized (24 vs 22mm). It makes for a nice case to strap size ratio. On to the watch itself... It's been on the winder for a few days and seems to be keeping pretty good time. I may pull up the atomic clock webpage and synchronize it tomorrow as it does have a "hacking seconds hand." Though I have noticed that the second hand sometimes studders, the watch still somehow keep pretty good time. I plan on wearing it for most of the weekend to get a real feel for it. I include a few pics with the 24mm strap.
