Citizen Spare Part 393-0049 (1 piece) – Ground Packing – NOS

Original Citizen case back gasket (Ground Packing) with reference 393‑0049 (Citizen item no. 91433930049) from unused old stock (NOS). A single piece is offered, taken from an original Citizen package (純正部品 / "5 PCS"). On the original label, the part is referred to as "パッキング" (Packing/Gasket); technically, it is the case back/cover gasket.

This gasket is listed, among others, for Citizen case reference 4‑580184, where it seals the case back (may also fit other references). It is essential for restoring the original water resistance.

The part is unused and ideal for the professional revision of classic Citizen watches, for which suitable original gaskets are hard to come by today.

Manufacturer: Citizen Watch Co., Ltd. (純正部品 / Japan).

Warranty (used) This is an original part (NOS) stored for decades. The limitation period for claims for defects (statutory warranty) is 12 months from delivery.

Note As this is an old stock gasket, the material may lose elasticity or become brittle due to age. Therefore, a guarantee of water resistance is not possible; the gasket should be checked before installation and only installed professionally.
