An improved watchcase construction in which the wrist strap is carried by a strap-retaining element slidably engageable with an end wall of the case bezel. The bezel includes channel-forming means in a rectilinear wall thereof, and the strap-retaining element includes an elongated channel-engaging member interconnected by a web portion to the remaining parts of the element. Detent means is provided to maintain the two elements in fully assembled condition, as is stop means for determining said position.
A bracelet watch comprises a removable flexible bracelet (2), the ends (5) of which are reinforced by an elastic tubular blade (6) or a cylindrical jaw inserted into a sleeve (7) removably fitting into a drilling (13) made in one side (1a) of the case (1) of the watch. A pawl mechanism (11, 16) is fitted for this assembly system.
An improved quarter-turn valve having an improved valve stem and handle is presented. The valve stem has four substantially square sides of desired predetermined dimensions and a top surface. The valve stem dimensions may conform to ISO 5211. The valve stem has a keyway extending vertically along one of its sides and a position indicator line extending diagonally across its top surface to positively indicate the status of the valve, whether open or closed. The valve handle valve handle has a substantially square bore that conforms to the side dimensions of the valve stem and a key that extends into the valve handle bore at a desired location. The key conforms to the dimensions of the valve stem keyway so that the handle may be attached to the valve stem only in a desired position with respect to the position indicator line so that the status of the valve, whether open or closed, is indicated by the valve handle as well as the position of the position indicator line.
The new wristwatch includes a wristwatch case including top and bottom parts and a watch movement within the case, a wristband including top and bottom band segments, each band segment having a first end part for engagement to the case and an opposite end part for engagement to the other band segment, and top and bottom coupling assemblies for releasably connecting the top and bottom parts of the case respectively to the top and bottom band segments, wherein the top coupling assembly includes an upper projection extending from the case top part, a recess formed in the first end part of the top band segment, the upper projection having height, width and depth dimensions adapted to fit into the recess, whereby the upper projection is essentially totally encompassed by the recess and invisible therein, and screw means adapted to engage and releasably join the first end part of the top band segment and the case top part. The bottom coupling assembly is similar to the top coupling assembly.
