- Movement - The technical name for the workings of a clock or watch, and does not include the dial or case.
- Rolled Gold - A type of gold plating devloped in the early 19th century, similar to Sheffield plating of silver, where the the gold is fused under pressure and heat to a base metal, usually brass, and then rolled into sheets of the required thickness.
The thickness of the gold plate can vary. In Britain the thickness of the gold is measured in microns. A micron is one-thousandth of a millimetre and 20 microns of gold is considered good quality. In the USA a differnt method is used that takes account of the total weight of the object.
Also, the purity of the gold, measured in carats can vary, with 24 carat being the purest. The gold in most rolled gold objects will be between 9 and 14 carats.
There are other chemical and electroplating methods of applying gold plate to a base metal, but rolled gold is considered a superior plate to a "gold plated" object.
Depending on the country and date of manufacture, the object may be stamped "Rolled Gold" or similar, but if there is any doubt as to whether an object is solid gold, or some type of gold plating, it is preferable to have it tested by a jeweller. - Keyless Watch - A keyless watch is a type of pocket watch or wristwatch that does not require a separate winding key to wind or set the time. Instead, a keyless watch is wound and set by a small knob or button located on the side of the watch, called a crown.
Keyless watches were first introduced in the late 19th century and quickly became popular due to their convenience and ease of use. Prior to the development of keyless watches, pocket watches were typically wound and set using a small key that was inserted into a hole in the watch case. The key would be turned to wind the watch's mainspring, and then turned again to set the time.
With the introduction of the keyless watch, watchmakers were able to simplify the winding and setting process by eliminating the need for a separate key. Instead, the crown on the side of the watch could be pulled out to set the time, and then pushed back in to wind the watch's mainspring.
The keyless watch design has since become the standard for most modern watches, both pocket and wristwatches. In addition to being more convenient to use, keyless watches are also typically more reliable and accurate than earlier models that used winding keys.
