- Condition and Functional Status
- The auction catalogue notes that the chronometer 'takes a wind and runs,' though the accuracy of the movement is not guaranteed. The general condition of the chronometer parts and cases is described as good, with light signs of age on the metal and wood, as well as cracking to the leather straps. The auction house clarifies that all lots are sold 'as is' and that condition reports are provided as a convenience, not as a full accounting of condition.
- Object Identity and Documentation
- This marine chronometer is attributed to the Waltham Watch Co. and is dated to the first half of the 20th century. The assembly includes a gimbal-mounted brass bowl, a brass-bound wooden inner box with a glazed lid, and a mahogany outer carrying case with leather straps. There is a discrepancy between the auction title, which identifies the object as an 'English' chronometer, and the markings on the brass bowl, which indicate US Navy service.
- Construction and Technical Details
- The timepiece features a white dial with Roman numeral hour markers, blued hands, and subsidiary indicators. The device is fitted with a fixed built-in winding mechanism. The chronometer is mounted in a brass gimbal. The movement's internal components and specific functions of the subsidiary indicators are not documented in the provided source material.
