Commentary:
This Waltham sidereal watch was purported to have been used by A.G. Stewart, ALS#078. Although it does not have the name “the Topley Company” on it, it is identical to a Waltham sideral watch shown in a 1911 Topley pamphlet: “Instructions Covering Astronomical Field Tables for the use of Engineers.”
The face of the watch is inscribed “WALTHAM”. The outer circle is graduated into 24 hours and 60 minutes. A smaller inner circle at the bottom of the face is inscribed “SIDEREAL” and is graduated into 60 graduations, presumably seconds of a minute.
Source of Object: Donated by C.H. Weir, ALS.
Notes: The Society has only one in their collection.
