Fume Watch dial

The Seiko MOD fume watch dial is a modification or "mod" to the original Seiko watch. This mod specifically refers to the dial of the watch, which has been changed to a "fume" style.
Fume dials are characterized by a color gradient that darkens towards the edges, giving it a "smoky" or "fumed" effect. This style of dial is often found in high-end luxury watch, but with the modding community, it has become possible to apply this style to more affordable watches like those from Seiko.
The Seiko MOD fume watch dial can come in different colors, such as black, blue, or green, with the color usually being lighter at the center of the dial and gradually darkening towards the edges. This modification can give the watch a unique and stylish look, setting it apart from the standard Seiko models.
