First Minute-Repeater Wristwatch (1892)
The world’s first minute-repeater wristwatch was unveiled in September 1892 by the Bienne, Switzerland firm of Louis Brandt & Frère, precursor to today’s Cheap Omega Replica company. Brandt had chosen Audemars Piguet in Le Brassus to modify a 13-ligne Lépine ébauche that Audemars had purchased from the ébauche maker LeCoultre & Cie. The striking mechanism was triggered by a slide at 3 o’clock. The complex wristwatch case strongly resembles that of a pocketwatch. Engraved on the dust cover is a phrase in French that translates as “Excluded from the competition: juror, Paris 1889.” The engraving suggests that the watch had been exhibited at the Chicago World’s Fair in 1893, but had not been allowed to participate in the competition for medals because César Brandt, who ran the firm with his brother Louis-Paul, had served on the jury of the Paris World’s Fair in 1889.
First Omega Wristwatch (1900)
The first wristwatches bearing the Omega name were produced in 1900 and used by British officers in South Africa’s Boer War (1899-1903). Omega was one of the first firms to begin serial production of wristwatches. The watches withstood the rough treatment they got. An Omega advertisement in a watchmakers’ magazine in Leipzig in 1904 publicized the testimony of a British artillery officer whose Omega Replica wristwatch performed admirably in bitter cold, searing heat, torrential rain and merciless sandstorms. The lieutenant colonel concluded that “The wristwatch is an essential campaign element.” The wristwatches were powered by a Lépine 12-ligne Caliber HN B and were available in two versions: one with the crown on the right, to be worn on the left wrist, and the other with the crown on the left for wearing on the right wrist.
Omega Constellation (1952)
Omega began using the name “Constellation” in 1952 to denote its officially certified wrist chronometers. The premier model was powered by Caliber 28.10 RA SC PC RG AM, which first appeared in 1945. This caliber wound itself via a unidirectional hammer-type winding weight. It also featured an indirectly propelled central seconds hand. The 28.1-mm-diameter, 5.4-mm-thick movement passed the official chronometer tests with flying colors. Its sturdiness, reliability and precision prompted Omega Replica Watches to produce the Constellation in large numbers. This model was also Omega’s first serially manufactured wristwatch chronometer.
Omega Speedmaster (1957)
The Omega Speedmaster, destined to become the most famous chronograph in the world because of its use by NASA for the Apollo program, was introduced in 1957. But the Speedmaster story really begins in 1943 with chronograph Caliber 27 CHRO C12, developed by Jacques Reymond. Born into a long-established family of watchmakers, Reymond had joined Omega’s subsidiary Lemania in 1942. The “CHRO” in the caliber designation stood for “chronograph,” the “27” referred to the movement’s diameter in millimeters, and “C12” denoted the additional counter for 12 elapsed hours. Further developed by Albert Piguet in 1946 and christened by Omega with the shorter name “321,” this movement was the smallest of its type at the time. Credit for the Speedmaster case design belonged to a group at Lemania, including designer Claude Baillod, prototype-maker Georges Hartmann and machinist Désiré Faivre. The Cheap Omega salient features were a black dial, luminous hands, a tachymeter scale, water-resistant case, screwed back and domed Plexiglas crystal. The diameter was originally 39 mm. A 40-mm version with the tachymeter scale on a black background along the flange appeared in 1960.
First Co-Axial Escapement (1999)
The Omega De Ville Co-Axial contained automatic Caliber 2500, the first wrist chronometer with a co-axial escapement. The escapement was invented by English master watchmaker George Daniels. Omega developed Daniels’s design so that it could be manufactured in large quantities. Caliber 2500 was a modified self-winding movement from Cheap Omega Replica sister, ETA. The co-axial escapement went a long way toward solving two fundamental problems that had plagued long- lasting precision timekeeping. First, every change in the viscosity of the lubricant oil detracted from the regularity of the rate behavior. Second, over time, the oil gradually disappeared from the locations where it was most needed in the movement. Daniels revised the architecture of the impulse-giving elements to reduce both the friction and the influence that the lubricant’s viscosity exerted on the balance’s amplitude. Unlike conventional escapements, his co-axial escapement consists of an intervening wheel, a co-axial wheel and a lever with three pallet jewels. The lever acts only when the balance swings counter-clockwise. To fully exploit the advantages of this escapement, 27-jewel Caliber 2500 had a Glucydur balance with a frequency of 28,800 vph and a flat, freely swinging hairspring.
