Claims
- 1. A method of making watch movements with sequential serial markings, comprising;
- making a recess in a surface portion of each of a series of plate portions of uniform watch movements, at a location which is visible during service and repair of the corresponding watch movement, the recess having a maximum extension over the plate portion which is small compared with a radius of the watch movement;
- fitting a series of plaques, each into one of the recesses, each plaque carrying a sequential serial marking; and
- attaching the fitted plaque to each of said plate portions, in the corresponding recess, to sequentially serially mark the watch movements.
- 2. A method according to claim 1 in which the attaching of each plaque is performed after substantial completion of assembly of the corresponding watch movement.
- 3. A method of making watch movements with sequential serial markings, comprising;
- making a recess in a surface portion of each of a series of plate portions of uniform watch movements, at a location which is visible during service and repair of the corresponding watch movement, the recess having a maximum extension over the plate portion which is small compared with a radius of the watch movement; completely assembling the watch movement corresponding with and including each plate portion; and
- thereafter fitting a series of plaques, each into one of the recesses, each plaque carrying a sequential serial marking comprising a set of more than three microscopically small symbols; and attaching each fitted plaque to the corresponding plate portion, in the corresponding recess, to sequentially serially mark the watch movements.
- 4. A method according to claim 3 including; providing a transparent film with sequential serial numbers thereon; and cutting said film into film portions to provide said plaques.
- 5. A method according to claim 4 including; providing said film with said numbers on one face thereof; and securing each plaque to the corresponding plate portion in the recess, with said one face downwards.
- 6. A method of making watch movements with sequential serial markings, comprising;
- making a recess in a surface portion of each of a series of plate portions of uniform watch movements, at a location which is visible during service and repair of the corresponding watch movement, the recess having a maximum extension over the plate portion which is small compared with a radius of the watch movement;
- securing each plate portion to an underlying element of the corresponding watch movement by fastening the element to the plate portion by a fastener disposed in said recess; and thereafter
- fitting a series of plaques, each into one of the recesses, each plaque carrying a sequential serial marking composed of microscopically small symbols, and attaching the fitted plaque to each of said plate portions, in the corresponding recess, to sequentially serially mark the watch movements and to seal the recess.
- 7. A plate and marker assembly for a watch movement comprising;
- a plate usable as part of a watch movement and uniform with plates so usable for a large series of such movements, the plate having a surface portion thereof disposed at a location which is visible and accessible during service and repair of the respective watch movement and having a recess in said surface portion which recess has a maximum extension over the plate which is small compared with a radius of the watch movement; and
- a plaque attached to the plate in the recess, substantially filling the recess, and carrying a sequential marking composed of more than three microscopically small numerals to distinguish said plate from the plates of the other watch movements of the series.
- 8. A plate and marker assembly according to claim 7, in which the plaque is transparent, has a surface secured to the plate in the recess, and carries said marking on said surface.
- 9. A plate and marker assembly according to claim 7, in which the plaque is a slab of metal having one surface imprinted with said marking and having its opposite surface secured to the plate in the recess.
- 10. A plate and assembly according to claim 7, also having an element at least partly underlying said plate; fastening means for securing the plate to said element; and means, including the plaque, for covering the fastening means, the plaque being substantially opaque.
