The Mastervolt AC Master power inverter produces a pure sine wave AC (Alternating Current) output from a DC (Direct Current) input from your boats battery bank. Because of the pure sine wave output, it is safe and reliable and prevents damage to the equipment it is connected to. The inverter is easy to install and features built in protection against over-temperature, overload, short circuit, high or low battery voltage and reverse polarity. The power inverter is robustly built and delivers the full output even in demanding conditions. The high frequency technology used eliminates noise typically associated with power inverters, such as buzzing or humming. It also features an automatic power saving mode, meaning a longer run time and less strain on your batteries. The 28211500 model is MasterBus compatible and can be used with remote control M70405080 for easy operation.

Cheap Quality - 3 MONTH wait for warrantied repair!
Color: Black-Red/Digital/Black
About 40 days into my purchase, the watch starts doing a complete reset when I try to reset the timer, making me have to reset the date and time again. The Analog watch isn't any more reliable -- sometimes it will just stop temporarily and start again. I'll look at my watch and see the analog time, then realize it's 15 minutes behind actual time.
So I called Timex for a warrantied repair. They told me I could send it in and it would take them about 3 MONTHS to repair it and get it back to me. 3 MONTHS, because they have to forward it to the Philippines for repair via the cheapest means possible. That is a ridiculous about of time to wait on a warrantied repair.

Looks great, but has issues
Color: Black-Red/Digital/Black
Great design, looks fantastic. Doesn't look too large, and the strap can be easily swapped for a nato strap if that's your preference. The negative display is quite readable and the indiglo works beautifully.
Unfortunately, like many others, mine was prone to the reset bug. Using the chrono or timer modes would send the watch into a sort of boot loop for several minutes, after which it would be factory reset to 12:00 AM. This bug only seemed to affect the digital display and not the analog hands. If you never used these modes then you'd never have an issue, but these are necessary functions for me so that made the watch a no-go, sadly.

Disappointing in many ways
Color: Black-Red/Digital/Black
Bought this model twice. Digital display failed on both, the first within the return window, the second just after. Timex customer "service" said to ship it back for a repair estimate, pay for the repair, and then it would take up to three months once payment was made. I said thanks, but I'll leave a bad review and get a Casio sooner.
