Abstract
A watch outer packaging component is a watch outer packaging component formed of austenitized ferritic stainless steel including a base formed of a ferrite phase and a surfacing layer formed of an austenitized phase in which the ferrite phase is austenitized, the watch outer packaging component abutting on a sealing member that partitions between a space inside a watch and a space outside the watch, wherein the surfacing layer includes an outer surfacing layer provided at an outer surface facing the space outside the watch, and an inner surfacing layer provided at an inner surface facing the space inside the watch, and the inner surfacing layer is thinner in thickness than the outer surfacing layer.

A watch outer packaging component formed of austenitized ferritic stainless steel including a base formed of a ferrite phase and a surfacing layer formed of an austenitized phase in which the ferrite phase is austenitized, the watch outer packaging component abutting on a sealing member that partitions between a space inside a watch and a space outside the watch, wherein
- the surfacing layer includes an outer surfacing layer provided at an outer surface facing the space outside the watch, and an inner surfacing layer provided at an inner surface facing the space inside the watch, and
- the inner surfacing layer is thinner in thickness than the outer surfacing layer.
A watch outer packaging component formed of austenitized ferritic stainless steel including a base formed of a ferrite phase and a surfacing layer formed of an austenitized phase in which the ferrite phase is austenitized, the watch outer packaging component abutting on a sealing member that partitions between a space inside a watch and a space outside the watch, wherein
- the surfacing layer includes an outer surfacing layer provided at an outer surface facing the space outside the watch, and
- the surfacing layer is not provided at an inner surface facing the space inside the watch.
A watch outer packaging component formed of austenitized ferritic stainless steel including a base formed of a ferrite phase and a surfacing layer formed of an austenitized phase in which the ferrite phase is austenitized, wherein
- the surfacing layer includes a first surfacing layer provided at an inner surface facing a space inside a watch, and a second surfacing layer provided at an outer surface facing a space outside the watch, and
- the first surfacing layer is thinner in thickness than the second surfacing layer.
