摘要： A double escapement mechanism for a watch, clock, or other timepiece. The mechanism comprises first and second escape wheels; a first geared drive wheel having a plurality of teeth for rotating the first escape wheel and a second geared drive wheel having a plurality of teeth for rotating the second escape wheel, the first and second geared drive wheels positioned below and concentric with the first and second escape wheels; a balance wheel positioned above the first and second escape wheels and mounted for rotational movement; a hairspring concentric with the balance wheel and positioned below the first and second geared drive wheels; a roller table having first and second impulse jewels positioned thereon and a roller jewel positioned therebetween; first and second arcuate levers for locking and unlocking the adjacent escape wheel and adjacent to the first and second escape wheels, each arcuate lever having a jewel positioned thereon for locking and unlocking the adjacent escape wheel; a passing spring having a blade positioned between the first and second arcuate levers and extending to the roller table, such that the roller table jewel can deflect the passing spring toward the first arcuate lever to unlock the first escape wheel and can deflect the passing spring toward the second arcuate lever to unlock the second escape wheel.

摘要： The invention relates to a method for bonding timepiece components, comprising applying an adhesive to a first and/or second timepiece component to be bonded to one another, and depositing an adhesion layer onto at least one of the first and second components to be bonded by spraying a primer composition in a localised joining area followed by the solidification of the primer composition. The adhesion layer is deposited prior to the application of the adhesive if the adhesive is applied to the one or more same components as the adhesion layer.

摘要： A detent escapement includes an escape wheel with teeth regularly spaced along a perimeter and a balance having an impulse pallet and receiving driving impulses via the teeth, the balance performing an alternation during which it receives a driving impulse and an alternation without a driving impulse, the detent escapement also including a hook pivotally mounted on the balance and held bearing by an elastic member against an abutment, the detent escapement including a pivotable detent which includes a first arm which collaborates with the escape wheel to block the latter before the start of the driving impulse, as well as a second arm to allow the escape wheel to disengage from its engagement with the first arm at the start of the driving impulse, and which limits the pivoting of this detent to only part of the oscillation of the balance, the detent being configured to again block the escape wheel after the latter has finished providing the driving impulse to the impulse pallet of the balance.
