This is one of the excellent Frankenized watches that resulted from the collaboration of Hyunsuk Seung and Yoonho Chung (AWI Certified Master Watchmaker). It is based on a Zeno 300 case which has been sandblasted to create a more military look. The watch has been heavily modified to produce this rare blend of military aesthetics and function. The original dome shaped plastic crystal has been retained along with the one-way rotating bezel. The dial has been replaced with a clean and legible custom Ministry of Defense (MOD) dial reminiscent of the dials on the recent Precista RN dive watches. The replacement movement is an ETA 2846 Automatic modified to provide the hack feature. Fixed strap bars have been added. This watch is tested for water resistance and rated to 300M. It has a screwdown caseback and crown to give you further confidence in its dive-ready construction. Pics of the actual watch shown at the bottom of the page. You can also see Hyunsuk's images of this watch at the following link.

This watch is sold as head only. The strap in the pic below is only for illustration. I am asking $450 for this fine example of Hyunsuk's work. I'll provide free USPS Priority shipping within US. Overseas shipments will be at actual cost of shipping. I have only worn this watch a few times, but have received many comments. It's in nearly new condition. It is one of my favorites, but a recent Seamaster 300 purchase has broken the bank, and, sadly, I must make a tough choice and sell this rare original (one of only one or two in this exact configuration).
