I recently bought a Mossimo watch with the analog and digital faces and the analog runs like ****. It keeps stopping and losing minutes. Like won't go accurate for more than an hour. Worse if it's being worn. Think it's just a battery issue, or am I screwed?

Normally this is the battery... Try the battery before considering to send the watch to Casio for service. Or, if you send it they will fix it and send it back. They are not very expensive for their service.

Go to "www.tissot.ch/" and at the bottom of page, click on "warranties".

Click on "user manuals" and enter details of your watch.

This is usually a indication that the minute hand is slightly loose on its pinion. This requires that the hand be tightened, so that it does not slip. Best left to a watchmaker.

If you have the Mossimo that is an analog and gisital andhas the four (4) buttons around the side, here is what I have:

Legend:
Button near the number 10 = A
Button near the number 8 = B
Button near the number 2 = C
Button near the number 4 = D

Switch Control/Normal Readout:
Press:
A = E.L. Backlight
B = Mode
C = For Month Date and Day of Week
D = For Alram Time

Setting Sequence:
1. In normal time readout, press B three times to get normal setting mode.
2. Press D once; Minute flashing, Press C to advance.
3. Press D once: Hour flashing, Press C to Advance (A on display = AM, P = PM)
4. Press D once: Date flashing. press C to advance.
5. Press D once: Month flashing, press C to advance.
6. Press D once: Day of Week flashing, press C to advance.
7, Press B once: Setting completes - returns to normal time readout.

Alarm Setting Times:
1. In noraml time readout press B twice, Alarm Time hour flashing, Press C to advance.
2. Press D once: Alarm Time minute flashing, Press C to advance.
3. Press B once:Setting Completed, returns to normal time readout.

Alarm Function
1. In normal time readout, arm alarm by pressing C and D simultaneously. Alarm signal will appear.
2. In normal time readout disarm alram by pressing C and D simultaneously. Alarm signal will disappear.
The alarm will stop itself after 1 minute or can be silenced by pressing D or press C with snooze feature - will re-alarm in 5 minutes for the next hour.

Chime:
1. In normal time readout, chime activated by pressing D and B simultaneously. All day flag appears.
2. In normal time readout, inactivate chime by pressing D and B simultaneously. All day flags disappears.

Chronograph:
1. In normal time readout, press B once to get into 'Chrono" mode. Pressing C will start the counting.
Two Options for "Chrono" mose:
a. Durning coutning, pressing C will stop count and then press D to reset the mark.
-Or-
b. During counting, pressing D will enter teh watch into laptime mode, meaning 1 portion of the count is registered on the display while the counting contiues until completed by pressing C, then D twice.

While in (digital) Clock mode (NOT in alarm setting mode!!!), push the bottom-right button and then the top-right, to toggle alarm on & off.

There is nothing wrong with your watch. Probably it's the one measuring heart rate and pulse (heart beats per second).
Use your users manual to set the watch.
By the way: Timex is one of the worst watch producers.

OK I'll do my best to describe the procedure...

Part 1:
Press mode button till the seconds window blinks
Press Lap/Reset button once to make minutes blink
Cycle through minutes using Start/Stop Button

Part 2:
Press Lap/Reset button once again to make hours blink
Cycle through hours using Start/Stop Button

(for this part, it's a bit tricky. Hours can be displayed in AM, PM, or 24 hour duration. AM is represented by "A", PM is shown with "P" and 24 hour mode is shown with "H", so keep an eye in the seconds window when setting your hour so you know for sure if you have the right hour)

When your done setting minutes and hours, press mode button again till you get to main screen
A helpful hint is to remember when setting up anything in this watch, mode will cycle through the different screens, lap/reset will change the value of whatever your modifying (AKA minutes/hours) and start/stop scrolls through the different fields.

Hope this helps. Sorry if it's confusing, best I could do.

FIXED!!!

As it turned out these Mossimo ANA/DIGI watches use two different batteries, one for the digital part (big) and other for the analog mechanism (small).

Have the watch serviced to change the second battery and VOILA!!!!

Enjoy!
