For sale today is a lovely 13s size pocket watch by Behring Strait. This watch is in good working condition and is keeping time well.

There is a small spot on the case back where someone scratched it to test the gold purity. Can probably be polished out nicely. Case size is approximately 50mm in diameter. 17-jewel Swiss made manual wind movement with push/pull crown. Movement reads "17 Fine Ruby Jewels" and "Fully Adjusted". Porcelain dial with blued-steel hands. Small sub-seconds. I don't know the exact age. I'm no expert on pocket watch design, but I think this would probably be about 100-115 years old. A very cool antique timepiece! Asking $115 USD OBO including shipping within North America. Great international rates available too.
