To provide a cover glass for watches which has a high hardness and excellent wearing resistance, is less apt to be marred even in long-term wear, and can retain antireflection properties. The cover glass for watches is characterized in comprising a transparent base and, formed on at least one side thereof, an antireflection film of a multilayer structure comprising a film of an SiO2 / Si3N4 mixture (hereinafter, referred to as SiON film) and an Si3N4 film, and is characterized in that the SiON film has been formed as an outermost layer. Due to the constitution, not only a satisfactory reflection-preventive effect can be obtained, but also the antireflection film has an increased hardness and significantly increased wearing resistance. Consequently, the antireflection film of this cover glass for watches, even in long-term wear, neither suffers fine surface mars nor peels off nor poses a problem, for example, that the fingers and dial become dim due to surface fogging. Furthermore, this cover glass retains antireflection properties.

A portable timepiece has a bezel rotatably disposed on a case body, and an elastically deformable gasket interposed between the case body and the bezel in an elastically deformed state to exert a frictional force on the case body and the bezel sufficient to maintain the bezel in a stationary rotational position though permitting the bezel to be manually rotated to any desired position by overcoming the frictional force. One or more lock members are movably disposed on the bezel and contact a slip-preventing part provided on the case body. A manually rotatable holding ring engages with the lock members and is rotatable in one direction to increase the contact pressure between the lock members and the slip-preventing part to thereby prevent unintended rotation of the bezel, and is rotatable in the other direction to decrease the contact pressure to thereby permit manual rotation of the bezel by overcoming the frictional force exerted by the elastically deformed gasket. In this manner, inadvertent rotation of the bezel is prevented by structure other than the gasket thereby preventing undue wear of the gasket.

A mechanical world timepiece having a transmission mechanism which allows the time display, such as, for example, a 12-hour hand and / or a 24-hour hand, to be directly adjusted with a turning ring having 24 time zones. The timepiece serves for the easily manageable adjustment of the time zone and the reading of the time in a different time zone. Operation could not be simpler. After a lever has been opened, the mechanism in FIG. 1 automatically engages. The gear rim (6), which is fixed with the turning ring, drives a vertical drive wheel (5), which is connected by a shaft to a clutch wheel (4). Once the pinion (4) is engaged, it drives one or two minute wheels (8, 9), which move a 12-hour wheel (10) and a 24-hour wheel (11) in a 1 h-cycle. The turning ring is thus easily turned to the desired destination at 12 h and the local time can immediately be read. Either the turning ring is now turned back to its original locality or the lever is simply closed. In the latter case, the time now continues running according to the set destination. The push-piece (2) disengages the mechanism via a rocker (3), simultaneously fixes, in the closed state, the gear rim (6) and prevents accidental adjustment of the time. The transmission mechanism can also be used for setting or changing other time displays, such as date, day of the week, month, year, minutes, or for other functions such as an alarm.
