The Barrel came in green and white gold and gold filled originally and then in yellow gold / gold fill later on. The models come as a Barrel Plain or Barrel Engraved depending upon the design of the bezel. The center case in both models is engraved.
Dials are predominantly luminous although I've seen a few black enamel dials - but they are quite rare.
I have wanted a white example for a long time and I always seem to wind up on the losing side of eBay auctions. Of course, Barrels in great condition are very desirable and I'm not the only one out there who likes them.
Last month I purchased a white Barrel Plain that apparently no one else wanted, as I got it for $55. As you can see in the photo below, it was in need of some serious TLC.
Well, it came to the right place. I overhauled the 17 jewel 987 movement, installed a new glass crystal, and had the dial and hands professionally refinished. With a new black lizard strap, this Barrel Plain is a welcome addition to the Hamilton fleet.
Here's a nice shot of the engraving of the center case.
Restoring a vintage watch is very rewarding. This was a very desirable watch when it was first purchased in the late 1920's. Obviously it had a long and arduous life but now it's ready for more wrist-time as a faithful timekeeper.
