I am finally ready to let go of this one... As with most time gages I build, especially the ones that come out really well, letting them go is not easy. This one represents more than 20h of intimate attention. I enjoy wearing it in my not so orderly rotation, but would like to purchase some new tools...

GPF Dual Time started its life as a brand new Parnis GMT. I bought it with the express intent of skeletonizing it.
I cut through the dial, through the GMT complication top and bottom plates, and through the main plate to expose as much of the moving parts as I deemed safe. The bridges seen through the exhibition back are also skeletonized and slightly decorated.

Despite the trauma of the cutting and filing I put this Seagull ST3600 through, it runs strong, long and even. Its been properly lubed upon reassembly.

The stainless steel case is 43mm in diameter (not including the crown) and 12mm thick. 22mm lug width with solid, screw bars. Its fully gasketed, but water resistance has not been tested, nor is it implied. Mineral glass crystal.

GPF Dual Time is a nicely executed, hand skeletonized, one of a kind time gage.
