# Antique American Waltham “Sidewinder” Pocket Watch – Model 1883. Up for sale is an antique American Waltham Watch Co. Pocket watch from late 1899. This unique piece features a hunting-movement configuration housed in an open-face case, placing the winding stem at the 3 o’clock position (familiarly known to collectors as a “Sidewinder”). Movement Serial Number: 9318529. Estimated Production Date: 1899 (September – October Run). Size: 18s (Large pocket watch size). Jewel Count: 15 Jewels. Movement Finish: Nickel (Damaskeened). Setting Type: Stem Wind, Stem Set. ### Case & Dial Styling. Case Type: Open face, screw-back configuration. Crown Position: 3 O’clock position (“Sidewinder” layout). Case Material: Silverode (Durable nickel-alloy base metal). Case Details: Features a clean coin-edge bezel and an elegant steam engine locomotive engraving on the back cover. Dial: Original porcelain dial with classic Roman numeral hour markers and a sunken sub-seconds register. Hands: Original blued steel hands. ### Condition Report & Mechanical Notes (Read Carefully). Cosmetics: The movement damaskeening looks brilliant. The silverode case shows normal light wear consistent with its age of 125+ years. Dial Condition: The porcelain dial features two faint, hairline cracks located between the 7 and 8 o’clock positions. Mechanical Function: The watch is currently wound tight and is not running. The balance wheel is wobbly when coaxed, which strongly indicates a broken balance staff pivot axle rather than a loose balance cock bridge. This is a perfect project watch for a hobbyist or watchmaker looking to install a new balance staff or transplant a donor balance assembly.
