Damaskeening
Damaskeening is decorative patterning on a watch movement. The term damaskeening is used in America, while in Europe the terms used are Fausses Côtes, Côtes de Genève or Geneva Stripes. Such patterns are made from very fine scratches made by rose engine lathe using small disks, polishing wheels or ivory laps. These patterns look similar to the results of a Spirograph or Guilloché Guilloché (; or guilloche) is a decorative technique in which a very precise, intricate and repetitive pattern is mechanically engraved into an underlying material via engine turning, which uses a machine of the same name, also called a ros ... engraving. The earliest known damaskeened American watch movement is E. Howard & Company movement SN 1,105, a gold-flashed brass movement with a helical hairspring. In the period between 1862 and 1868, the same Boston firm damaskeened approximately 400 Model 1862-N (Series III) gold-flashed movements as well, and about 140 nickel-plated brass mov ...

Guilloché
Guilloché (; or guilloche) is a decorative technique in which a very precise, intricate and repetitive pattern is mechanically engraved into an underlying material via engine turning, which uses a machine of the same name, also called a rose engine lathe. This mechanical technique improved on more time-consuming designs achieved by hand and allowed for greater delicacy, precision, and closeness of line, as well as greater speed. The term ''guilloche'' is also used more generally for repetitive architectural patterns of intersecting or overlapping spirals or other shapes, as used in the Ancient Near East, classical Greece and Rome and neo-classical architecture, and Early Medieval interlace decoration in Anglo-Saxon art and elsewhere. Medieval Cosmatesque stone inlay designs with two ribbons winding around a series of regular central points are very often called guilloche. These central points are often blank, but may contain a figure, such as a rose. These senses are a ba ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Watch Damaskeening
A watch is a portable timepiece intended to be carried or worn by a person. It is designed to keep a consistent movement despite the motions caused by the person's activities. A wristwatch is designed to be worn around the wrist, attached by a watch strap or other type of bracelet, including metal bands, leather straps or any other kind of bracelet. A pocket watch is designed for a person to carry in a pocket, often attached to a chain. Watches were developed in the 17th century from spring-powered clocks, which appeared as early as the 14th century. During most of its history the watch was a mechanical device, driven by clockwork, powered by winding a mainspring, and keeping time with an oscillating balance wheel. These are called ''mechanical watches''. In the 1960s the electronic ''quartz watch'' was invented, which was powered by a battery and kept time with a vibrating quartz crystal. By the 1980s the quartz watch had taken over most of the market from the mechanic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rose Engine Lathe
A rose engine lathe is a specialized kind of geometric lathe. The head stock rocks back and forth with a rocking motion and/or slides along the spindle axis in a pumping motion. A rosette or cam-like pattern mounted on the spindle is controlled by moving against a cam follower(s) while the lathe spindle rotates. Rose engine work can make flower patterns, as well as convoluted, symmetrical, multi-lobed geometric patterns. The patterns it produces are similar to that of a Spirograph, in metal. No other ornamental lathe can produce these "rose" patterns. The decoration produced by a rose engine lathe is called guilloche. It sometimes confused with "jewel finishes" or engine turning, a much cheaper process of making swirly marks in metal by a rotating abrasive peg or pad, which is repeatedly applied to the surface to make a pattern of overlapping circles. Jewel finishes used to be common on stereo faceplates and automobile interiors. The patterns of United Kingdom's first postage s ...

Spirograph
Spirograph is a geometric drawing device that produces mathematical roulette curves of the variety technically known as hypotrochoids and epitrochoids. The well-known toy version was developed by British engineer Denys Fisher and first sold in 1965. The name has been a registered trademark of Hasbro Inc. since 1998 following purchase of the company that had acquired the Denys Fisher company. The Spirograph brand was relaunched worldwide in 2013, with its original product configurations, by Kahootz Toys. History In 1827, Greek-born English architect and engineer Peter Hubert Desvignes developed and advertised a "Speiragraph", a device to create elaborate spiral drawings. A man named J. Jopling soon claimed to have previously invented similar methods. When working in Vienna between 1845 and 1848, Desvignes constructed a version of the machine that would help prevent banknote forgeries, as any of the nearly endless variations of roulette patterns that it could produce were ext ...
