The Seiko caliber V192 (actually marked V192A) is a solar powered chronograph movement with a power reserve indicator. This caliber is made in Japan and is found in Seiko branded timepieces. This caliber is part of the Seiko Watch Corporation V (VXXX) family/series of solar powered movements.

V192 VS V194:

There is a similar Seiko caliber V194 with the main difference between the two being that the calendar complication on the V194 is in the form of a double digit big date at 12:00. The V192 discussed on this page has a standard date window between 4:00 and 5:00. All of the other features and functions are the same.

Accuracy:

Seiko claims that the caliber V192 will maintain accuracy of +/- 15 seconds per month at normal operating temperatures of about 5C to 35C (41F – 140F).

Battery Change:

The caliber V192 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 (because not all MT920 are the same): part number 302324D (3023-24D).

Charging Times:

The chart below shows how long different lights sources can take to fully charge the cell in the V192. This ranges from 150 hours to 5 hours of constant light source. The following excerpt is from the official Seiko manual.

Power Reserve Indicator:

The Seiko V192 features a handy power reserve indicator on the dial at around 7:00. This indicator is positioned to the left of the 60 minutes chronograph totalizer and uses the 60 min chrono hand to display the remaining charge that is being stored in the capacitor. The following instructions show how to use the indicator:

A full charge can last up to 6 months. Seiko states that this power reserve is based on only using the chronograph for less than one hour per day.

Interesting Note:

Although there is an instruction manual for dive watches with caliber V192, there is also another instruction manual that combines the following calibers: V192 and V194.

I recently purchased a Seiko V192. I love it. I had to download the instructions manual but that was no problem. It works great. It was worth the investment!!!!

I opened both of my solar Seiko Speedtimers, an SSC909 (limited edition with ice blue dial) and the newer SSC911. Both have the same movement: V192A marked “no jewels” and “Japan.” Both casebacks are marked inside “Seiko Time Corp R China case.”

I got the v192-0ad0 to be specific. This watch is -0.25 seconds per month when warn, and +0.25 seconds per month when left alone on the table at 20C room temperature. It doesn’t get better than that.
