Can I offer a suggestion?
Since the DW6263 uses an modified A7750 to A7760...Could you not procure a Valjoux 7736 and use that instead? I've been seriously looking into a DW6263, but didn't like the thought of the modified A7750 and can't afford a V72 right now. The 7736 beats at 18,000 just like the V72 and is a true manual wind movement and I also believe that the sub-dial spacing for the 7736 would be the same as the 7750. So fitting the dial onto the 7736 shouldn't be an issue.
I haven't picked up a DW6263(7750)to try it out yet, but it is on the top of my list as a watch to buy.
Just a thought...
On an interesting note - my little girl cracked her head open this summer camping and when we went to the hospital, they used a hospital grade superglue...I asked the doctor what is the difference the stuff that hospitals use and the stuff bought off shelves.
He said that the off the shelve superglue contains cyanide. You should use it an emergency situation. If you use superglue all the time to close wounds, it is better to use a medical grade superglue.
The Seamaster 300 is a beauty...here's mine with gen crystal, second hand, bracelet and caseback. I have a gen replacement bezel, but haven't decided to install it yet, just because I like the look of the bezel with the rest of the watch. Plus I'm looking for the correct dial and that is a quest in itself...
