    Changing batteries was no HELP, sent both stopwatches to Coserv-Mahwah to fix in Apr. 2011. Stopwatches returned in tip-top shape. Paid hefty price for fixing but worth paying than buying new ones at a price of $400. + dollars for 1 stopwatch only.

    What model Seiko? Is it the stopwatch/printer S149?

    I have been doing a little research. Your unit may be the S129. I believe it has 4 batteries for the printer and 1 lithium button type battery for the stop watch. I would change the lithium battery or at least check it. I should read 3 volts. If it is anything less change it. Then look for a way to "reset" the stopwatch". This may be a button, or two surfaces on a circuit board under or near the lithium battery that are short circuited together with metallic tweezers or a metal circuit board pad that shorts to the battery in the same manner. If this fails you are stuck as there are no further user remedies. Call New Jersey and ask for tech support. Your repairs are likely covered by a warranty. Ask.
    Pay attention to the battery before you remove it so you get the new one in correctly. I will try and find out the battery number and get back to you. Michael

    The button battery is a CR 2032, pretty common battery, should last years, should cost around 5 bucks

Hi, got a seiko 7T92, the stopwatch second hand, can this be made to work as a second hand or is it only for the stopwatch function, it's annoying that it's still all the time!

If you can have both clocks running at same time, yes but they'll be on different screens. you just have to go back and forth between screens.

How much is the capacitor problem in Seiko SNL001 or similar model watches as I get to read reviews abt' capacitor problems appearing in Seiko kinetic watches after 3-4 years and the repair also happens to...

Can be fixed in less than one week and cost is less than $80. See web site for Timelywatch They guarantee their work. And yes, the old capacitors are only good for 3-4 years. All replacements are now with a much better, long lasting Lithium Ion battery.

The Seiko s149 will not display anything on the screen.

We had to change the internal battery on ours today. There are 4 screws on the back of the case and 3 inside the AA battery compartment. Careful pulling the front and back apart as there are some wires that attach between the two. Two of the three screws need to be removed to get the CR2430 battery out to replace it. We now have the watch screen...just need to remember how to operate it...need a new users manual.

Second hand doesent return to 1200 position after replace batt

I just replaced the battery in my 20yr old Seiko chrono sports 100. And I had the same problem. I think I stopped it on 12 while in stopwatch mode and held down the start stop button and the set button at the same time. See if that works dude.
