If you like meaty then this is your dream weighing in at 146 grams. The checkerboard just has great detail. This movement probably needs cleaned but is worth the trouble. That’s a big range for what should be the same watch. The problem is they are not all the same. My guarantee is that every pocket watch I offer comes from a watchmaker or retired watchmaker’s inventory. This means that only professionals have handled it. Please assume this watch needs serviced and regulated. Please use the photos as a big part of the description and please contact me with any questions.

This is a beautiful piece of history. And a great conversation piece. The fact that it tells time is just a bonus. You can feel safe with this one, it’s a soft wind and feels durable. I grew up in the early’70s and I would have never guessed that’Sears and Roebuck’ would be highly collectable. This watch is smooth winding and feels good in your hand. That’s a big range for what should be the same watch. The problem is they are not all the same. My guarantee is that every pocket watch I offer comes from a watchmaker or retired watchmaker’s inventory. This means that only professionals have handled it.
