American Brand: The History of Bulova Through 10 Milestone Bulova Watches


Another British Military watch on the blog this time, and something of an enigma. The watch is very similar in style and size to the W10 made by Hamilton from and subsequently by CWC from and it shares all of the attributes required to adhere to the strict standards for military use. The case is opened by removing the crystal and splitting the two-piece stem, and inside is a 17 jewel, manually wound calibre made by A. It has a higher beat rate, 28, bph as opposed to 21, bph, and also has a micro-adjustment mechanism mounted on the balance cock for more accurate regulation. Here is a picture of a cal. In the picture above, the stem is pushed all the way in — in the winding position — and so the stem presses on hacking lever, it pivots around the fixed axis just above the castle wheel and the lower arm of the lever releases the balance allowing it to rotate freely. The watch arrived in decent condition and needed no more than a movement service, a crystal polish and an ultrasonic clean for the case, so here it is all back in one piece.

The movement in this watch is a Lemania cal. What makes this calibre interesting, both technically and visually, is that the minute register for the chronograph is not presented in a subdial, but as a separate minute hand that sweeps around the dial.

Caravelle watches are made with proven and established technology, and the company puts their focus on design.

They make a number of chronograph models and a couple of interesting models with skeleton faces that allow you to see the parts of the movement. You will have to have the battery replaced every couple of years.

Bulova Watch Identification Guide

Clock-watch[ edit ] The earliest dated watch known once belonged to Philip Melanchthon and is now in the Walters Art Museum , Baltimore The first timepieces to be worn, made in the 16th century beginning in the German cities of Nuremberg and Augsburg , were transitional in size between clocks and watches. Nuremberg clockmaker Peter Henlein or Henle or Hele is often credited as the inventor of the watch. He shapes many-wheeled clocks out of small bits of iron, which run and chime the hours without weights for forty hours, whether carried at the breast or in a handbag However, other German clockmakers were creating miniature timepieces during this period, and there is no evidence Henlein was the first.

They were heavy drum-shaped cylindrical brass boxes several inches in diameter, engraved and ornamented. They had only an hour hand. The face was not covered with glass, but usually had a hinged brass cover, often decoratively pierced with grillwork so the time could be read without opening.

Bulova marks the date on their watch cases and movements as follows. On the back cover of the watch, below the serial number at the bottom there is a tiny date .

This is probably the most common question watch collectors have. Sometimes it is easy to answer, and sometimes it is impossible. There have been a lot of watch manufacturing companies that have come and gone over the years. Many have gone out of business, while others destroyed records to save space. Some companies as with the Gruen Watch Company , even lost rocords to fire or other natural disaster.

The companies are not to blame. I am sure they had no idea that their timepieces would someday be collected. There are several ways to get an idea of when your watch was made. I am slowly adding serial number tables to this site. Serial number records are available for many of the old pocket watch companies like AM Waltham, Elgin, South Bend etc. If serical number records are available for your watch, here’s how to use them: You will notice that there are many numbers stamped at various locations inside and outside your watch.

Aaron Berlow June 22, Quartz. We pretend it’s not there, but it defines the modern world of watchmaking. And yet, once upon a time, it was the new kid on the block –an unknown quantity whose influence had yet to be felt. We’re very pleased to present to you one of the most important and influential watches you’ve probably never heard of: Our watchmaker-in-residence, Aaron Berlow, takes us inside this groundbreaking movement, which influences quartz timekeeping design to this day, and shows us what makes it tick.

Asking many watchmakers what they think about quartz is like asking a die-hard American conservative what they think about government regulation. There is a visceral hatred of this technology that was both so much more accurate and so much cheaper than mechanical movements. It very nearly turned Swiss watchmaking into American watchmaking that is to say, obsolete.

This disdain has led to some amazing innovations and some incredible oddball pieces that are often swept under the rug. The Beta 21 movement is one example that is rapidly gaining appreciation and value, as evidenced by their 5-figure auction estimates and results. This Girard Perregaux Quartz is really an unsung hero of the quartz world.

History of watches

A Hamilton US military “general purpose” watch from In keeping with similar watches of this type, the dial bears the “H3” mark which I think signifies the use of Tritium in the luminescent compound and the Radiation tri-foil symbol.

The last Elgin movement made in America was produced in In between, pinning an individual Elgin down to a specific year and model can be a bit of a chore. Starting around , Elgin used model numbers to identify unique case designs. In the s, the use of model numbers was supplemented by individual model names. The model numbers remained, however, and are the key to finding replacement parts for Elgins of the period. Identification of a watch is a process, typically done as follows: First, establish that the watch is, in fact an Elgin.

Second, attempt to identify the model by matching the case to known examples or to identification resources. If that fails, identify and date the movement to narrow your search and try again to identify the case. We look at each of these issues, below. Is it really an Elgin? The case back can also provide insight into the manufacturer. The presence of a signed crown will add another piece to the puzzle, however, they were not used for all, or even the majority, of models.
