My grail just arrived, a '57 Benrus Dial-O-Rama! Been hunting for what seemed like forever for an example that didn't have a butchered second pinion (many, many of this model do). Had an hour disc that snapped sharply on the hour, and one that didn't carry an outrageous price tag. You can find examples on ebay for $500 - $900! This one actually found me after I posted a comment in our WRUW thread. And it met all three of my criteria. It's a beautiful example and I'm forever in debt of "Just 1 More"
It arrived in really good running order and keeping excellent time. Just in need of some TLC, a good cleaning up and a new crystal. The original crystal had broken off leaving the rim of the old crystal stuck inside. Removal is a unique process for this model. The Dial-O-Rama's case back, movt., retaining ring and crystal are press fit as a single assembly into the case bezel. You have to press them out backwards as a unit by applying pressure from the top of the crystal downward. Once known it isn't a difficult task as uniform downward pressure is applied to the crystal top. However, this watch didn't have a crystal and a press die that fit exactly on the old crystal rim was needed. Placing pressure on the dial would destroy it.
Misson accomplished. A NOS crystal obtained, still in its original envelope. The old crystal to the right was just used to protect the dial in transit. It was taped to the case. The cleanup process will begin and then the new crystal and movt pressed back into the case.
