Waltham Pocket Watch Antique Pocket Watch Working It is in working condition. I took three consecutive photos, and you can see that the second hand is moving. You can set the time by pulling the crown. I have not measured the daily rate. There are minor scratches on the old item, so please check the photos. How about it for those who like it? I opened the back cover and examined it below. Waltham Colonial B (1924 Colonial) "Royal" 12 size 17 jewels 3 pos. adj. 1925 Waltham 12 size, Colonial B (1924 Colonial) "Royal", 17 jewels, 3 pos. adj. steel case, c. 1925, U.S.A. The movement (the internal mechanism of the watch) of this item is the "Colonial B" developed by Waltham in 1923. The "Colonial B", also known as the "1924 Colonial" and "Grade 1225", is a 12-size dress watch specifically designed to be thinner than the usual 12-size movement. As you can see in the photo below, the "Colonial B" is very similar to the "1894 Colonial" of the same size, but it is even thinner than the "1894 Colonial". The "Three Positions Adjusted" (3 POS. ADJUSTED) engraving indicates that the balance wheel has been designed and manufactured with particular precision so that there is no difference in the rate of timekeeping in three positions: "dial up", "dial down", and "12 o'clock up", which is a sign of a high-end watch. This watch is a "17-jewel" hand-wound movement using 17 rubies, which is a high-quality construction that uses rubies in all the necessary places. All the jewel holes (rubies) are protected by gold chatons. The "Colonial B", also known as the "1924 Colonial", was developed and released in 1923, regardless of its name, and the serial number of the first unit is "23,285,001". From the 8-digit serial number "24,323,135" engraved on the mainspring barrel bridge of this item, it can be seen that this watch was made around 1925. The "Colonial B" is a high-end machine that anticipated the times with advanced technology, even though it is an antique movement developed about 90 years ago, and it is still practical today.
