Hi All of that sounds so simple. Unfortunately there are lots of little details. Back a long time ago the very large outfit I worked for decided to make quartz watch movements. It's just electronics.
There were about five of us who did work on the watch electronics. I was involved with the analog (stepper motor) design. They also had an LCD design. To this day I prefer stepper motor versions of the quartz movement. Likely that's designer bias. Lots of little details and you have to get them *all* right. They focused on the timing side of it, got that right. There were a few reliability bumps, got them straightened out quickly. Technically they were a fine little group of gizmos. They missed what one might call the fashion side of it - bad move. Watch cases come in two basic sizes. You don't make a movement that's to big for the small case and to small for the big one - double bad move. They also got caught making it all themselves - triple bad move. Net result was about a $100 mil loss (in 1970's dollars) and an exit from the market / sale of the brand name. Timing technology is not all of it.

The term ebauche, is very similar to the term engine block. An ebauche is an unfinished movement. It typically has not been fitted with all of the jewels, balance, etc.. In Switzerland, like in Detroit, there are numerous companies, also known as Ebauche, that build the parts that many name brand manufacturers assemble into a finished unit... be it an engine, or a watch. Just as a Volkeswagen Beetle, and a Porsche 914 use the same engine block, but finish it for different purposes, an ebauche movement may receive quite a lot of hot-rodding depending on the OEM customer. Some get their plates dressed up with fine gilt lettering, Damasceening, extra jewels, and adjustments, and others simply get stuffed into the watch case rough and unadorned. The term calibre, is used two ways. The first is to show the general size of a movement, in lignes. The second is to indicate the general layout, or style of a movement. Movements of the same calibre can often be substituted for an original movement, even though they are made, and finished, differently than the original. Companies like Rolex have traditionally done all of the manufacturing of their movements in house. They do not use the Ebauche market as a source for any of their parts. Other companies, like TAG/Heuer use nothing but Ebauche parts. Quartz movements as found in the typical Bling brands, are all ebauche. Mechanical watch movements have suffered greatly from the rapid depression of the prices of sophisticated electronics, and the rapid rise of labor costs. It was once possible for a watchmaker to spend his days fixing watches, at a reasonably cheap price, and still keep his wife and kids fed clothed, and living in a decent home. But even back then, technology brought us the "Dollar Watch" that was so cheap that it was never meant to be fixed. The start of the downfall of the watchmaking profession. Today, if a watchmaker charges $140 for a 3-4 hour service job, people complain that it is too expensive. And yet, they would also complain if they didn't get more than $140 for 3-4 hours of their time. -Chuck Harris William H. Fite wrote: > That estimate is probably about right.
