Unitas 6498 Watch Movement

Unitas was a Swiss ebauche movement manufacturer established in 1898, joining Ebauches SA in 1932, and still in existence as part of ETA. In watchmaking, this is the general term for the basic movement parts, such as the movement plates and bridges, and mainspring barrel. In modern watchmaking, this is a complete movement kit, minus the escapement components (which may also be supplied to the final assembler). Auguste Reymond established his namesake watch company in 1898 in Tramelan. Like most watchmakers at the time, he used movements from a variety of producers before beginning ebauche production on his own around 1906. Movement production began in Bioux but was moved to Tramelan soon after. Reymond purchased the existing Unitas Watch Company in 1926 and used that name on his ebauches, movements, and some complete watches. In 1932, Reymond and Unitas came under the ASUAG umbrella, with the Unitas ebauche operation falling under Ebauches SA. The Unitas trademark stamp, a letter “T” inside a letter “U” was established at this time. In the 1950’s, Unitas released two famous pocket watch movements, calibres 6497 and 6498. These large (19 ligne) hand-wound movements would continue in production until the present under the ETA banner. Cal. 6498 is a large pocket watch movement produced by Unitas and ETA since 1950 and continuing until the present day. Overview The Cal. 6498 family is a Savonette or hunter pocket watch calibre and thus has the sub seconds dial at 6 00, 90º off-axis from the crown and winding stem, but is closely related to Cal. 6497, the Lépine version. It is a large movement, measuring 36.6 mm in diameter but is only 4.5 mm thick thanks to a compact manual winding design. Modern 6498's are fully jeweled (17 jewels). Most 6498's operates at 18,000 beats per hour. Power reserve for modern versions is 46 to 50 hours. Although developed for pocket watches and far too large for the small wrist watches that were popular in the 1950's, the advent of large sports watches has made Cal. 6497 popular on the wrist. In particular, Panerai brought the 6497 to popular acclaim, though they do not use Cal. 6498. Makers who use Cal. 6498 include Eberhard, Longines, Martin Braun, Maurice Lacroix, Sinn, TAG Heuer, and Wempe, Panerai's OP X caliber. Cal. 6498 is also the most-widely used teaching movement in watchmaking schools, making it very well-understood by watchmakers. Movement Cost around $160US on ebay
