Exhibition Case or Back Unique complication wherein a crystal window is implemented into the back of a watch case, allowing view of the timepieces movement. Function Pushers Manual controls on a case for when a movement features complications that require increased manipulation. Greenwich Mean Time GMT Also referred to as Greenwich Meridian Time, the Greenwich Meridian Line is located at the Royal Observatory in Greenwich, England. It is the place from where all time zones are measured. Greenwich Mean Time is the average time that Earth takes to rotate from noon to noon. Welcome To Kimball Sterling, Inc., Auctioneer and Appraiser, Outsider, Fine Art, Antiques,Estates, Antique Canes, Antique Cane Auction, Antique Cane, Antique Canes. In this regard, GMT is thought of as the worlds time and was once the basis with which every other zone set time. Guilloche Style of engraving that features wavy or straight lines, giving a unique effect when the timepiece is moved or shifted. Ionic Plating Process that produces a hardened surface that is durable and scratch resistant Has a black flat stealth finish. Jewels Within a movement, metal on metal contact creates wear and tear. Watchmakers use jewel bearings to reduce friction and help the delicate parts of the movement work smoothly and with great precision. Jewels help extend the movements life. Diamonds, sapphires, rubies and garnets are the preferred materials. As a general rule, a higher number of jewels suggests a more prestigious movement. Lugs North and south ends of the case that attach to the strap or bracelet and often extend out from the dominant lines of the case. Moon Phase The lunar cycle has been a cornerstone of horology, the study of measuring time, since ancient days. Moon Phase is a complication on a timepiece that displays the various stages of the moon cycles from waxing to waning. It appears as a dial visible through an aperture which reveals the current moon phase. Movement Assembly making up the principal elements and mechanisms of a watch or clock Includes the winding and setting mechanism, the mainspring, the train, the escapement and the regulating elements. Www. AuthenticWatches. Below is a part of our tens of thousands of feedbacks we have received in the past decade. The portrait of a man with a secret sex life who preached to thousands and then slept with members of his congregation has emerged. Power Reserve Time a watch will continue running based on the movements residual winding of its mainspring In quartz and digital watches, this can also refer to the amount of energy left in the battery. Push Button Dual Deployant Similar to deployant and considered one of the most desirable and easy to use clasps, the push button dual deployant employs two small hidden push buttons that release the bracelet. This clasp keeps the closing mechanism hidden for an uninterrupted, seamless finish. Repeater Complex watch mechanism that sounds hours, quarters or minutes, or repeats them on request Originally designed to help the wearer to tell the time in the dark. Retrograde Hour, minute, second or calendar hand that moves across a scale and resets to zero at the end of its cycle. Skeletonization Reveals the intricate symphony of moving rotors, gears and springs which power a timepiece The open design offers an insiders view, as unnecessary metal is cut away to allow the wearer to actually see the movements skeleton. Swiss Made Since the 1. Switzerland has been the epicenter of watch making, producing some of the industrys greatest technological advances. The Swiss put a law into effect for all timepieces baring the words Swiss Made First, the movement must be assembled in Switzerland. Secondly, the movement must be cased up in Switzerland. Finally, the manufacturer must carry out the timepieces final inspection in Switzerland. Tachymeter Scale on a watch used to determine units per hour, such as average speed over a fixed distance, or distance based on speed Typically located along the outer rim of a dial. Tritium Miniature tubes containing gaseous Tritium and layered with phosphor to power the luminous accents which can be seen for several meters in darkness. Tritium illumination requires no electrical power but must be charged by holding your watch close to any light source. The longer you hold it there, the longer and brighter youll see the Tritnite. Unidirectional Rotating Bezel Used for tracking elapsed time. A ratchet mechanism prevents the bezel from rotating backwards. This feature is popular with divers, who rely on the elapsed time feature to prevent the diver from running out of air. The fact that the bezel cannot rotate backwards prevents the wearer from underestimating the elapsed time. About Stainless Steel Also called corrosion resistant steel, stainless steel is a steel alloy with added iron and chromium. The metal is rust resistant, durable and highly lustrous. It has a similar appearance to platinum and polishes to a glistening sheen. Any scratches that may occur from day to day wear can be easily buffed away without endangering the piece. Please note, however, if the stainless steel is plated with another metal, the plating can wear off if rubbed excessively against hard surfaces. Stainless steel was first recognized in France in 1. Pierre Berthier. After several corrosion resistance related discoveries and patents in Europe and the United States, Harry Brearley in England discovered a modern blend of stainless steel alloy. When it was announced by The New York Times in January of 1. Quartz Although not as mechanically complex as other engines, the quartz movement provides the most accurate and reliable time keeping. This type of movement typically draws power from a battery and centers around a small vibrating chip of quartz crystal. When an electrical current, supplied from a battery, is applied to a quartz crystal, the current is distorted and creates a precise resonating frequency. Watchmakers employ the subsequent frequency to measure time. Some adaptations to the traditional quartz movement include introducing rotors and power cells in an effort to maintain the accuracy of quartz while eliminating the need for a battery. Quartz movements have been used in timepieces since the 1. The case provides the foundation for all other major watch components.
