WATERPROOF WATCH FRAME Russian patent published in 2021 - IPC G04B37/00 

FIELD: watches.

SUBSTANCE: area of application: the invention relates to the frame of a waterproof diving watch. Substance: the frame (1) of a waterproof diving watch is comprised of a back cover (4) installed on the bottom of the frame ring (2) and glass (3) installed on the top of the frame ring. The glass (3) has an annular peripheral surface (13) attached by means of a first section (5) of an annular liner, wherein said section is made of amorphous metal, to an inner annular surface (12) of a matching shape located on the top side of the frame ring. A second section (5') of the liner located on the first section of the liner holds the glass on the frame ring. The annular peripheral surface of the glass is inclined inwardly relative to the watch frame at an angle less than 90° relative to the central axis perpendicular to the plane of the watch frame to distribute the stresses caused by the water pressure during immersion between the glass and the frame ring. The annular peripheral surface and the inner annular surface are tapered.

EFFECT: provided is possibility of a waterproof watch frame to withstand high water pressure when submerged deep underwater.
