The Seiko caliber V158 is found in some Seiko solar-powered watches, including the exclusive Street Series Solar Divers. This caliber is part of the Seiko Watch Corporation V family/series of solar powered movements.

V158 VS V158A:

The movement in your timepiece may actually be signed with the caliber number V158A. As with all Seiko movements, the trailing letter indicates the evolution or change-log of the movement, starting with A as the first release. Therefore, V158 is the same as V158A. As of this post, there is not a V158B, V158C, and so on.

V158 VS V157:

There is a similar Seiko caliber V157, with the main difference being that the V157 only has a date window at 3:00, and the V158 has a day/date at 3:00.


Seiko claims that the caliber V158 will maintain accuracy of +/- 15 seconds per month at normal operating temperatures of about 5C to 35C (41F – 140F).

Battery Change:

The caliber V158 is a solar powered watch with a manganese titanium-lithium rechargeable capacitor. It is not a normal battery. The number is MT920, or more specifically: 302324Y. Order one here

Charging Times:

The chart below shows how long different lights sources can take to fully charge the cell in the V158. This ranges from 120 hours to 9 hours of constant light source. A full charge can last up to 10 months.

Interesting Note:

Although there is an instruction manual for dive watches with caliber V157 or V158, there is also another instruction manual that combines the following calibers: V110, V111, V114, V115, V116, V137, V145, V147, V157, V158, V181, V182, and V187.

I love my little solar 158. In about 6 weeks it has gained only about 5 seconds. Seiko rules when it comes to bang for buck. Great looker. Nothing in this price range rates.

Had charging issues when new. then it died, left on window sill for a month and came back to life! Keeps about 1 sec per week. SNE393.

I have had my solar-powered Seiko V158 for over 2 years and love it, and this is my second Seiko. My first lasted 25 years. I love the RR styling! The indoor lighting keeps it running – no problems with lack of power. Time keeping is never a problem, and since they set it at the store for me when purchased, I have not had to reset it, ever!

I have had my V158 since Oct 2016 and its never worked for longer than a day. Put it on a window ledge in sun and it goes for 10mins then shuts down. Charge it under a fluro desk lamp runs for a few hours the stops. Mechanism changed under Warentee still didnt work. Gave up but am retrying now?

I was given a watch today with the V158 within. It’s been in the back of a dresser drawer for at least 5 yrs, according to the kid donor, and once I exposed it to some sunlight it immediately came to life!
