Welly MerckWM Watch - WM142 Moon Phase Watch 41mm Modified 7200A Watch 5ATM Men's Automatic Watch

It keeps excellent time but the moon phase is ridiculously inaccurate. I set it at the full moon this month and it’s already on the rise at waxing crescent with the actual new moon not due for 2 more days so it gained 4-5 days in less than 1/2 the moon cycle.Considering that you buy a moon phase watch specifically for the moon phase function I’d say this is worthless and you’re better off with a $30 Timex, at least that gives you the date.EDIT: I am upgrading my original rating of 1 Star because WM Watches reached out to me to help with the problem and they are replacing the watch free of charge. While my watch does have a problem with the moon phase, the design of the watch is to have a 31 day moon cycle which is a bit longer than the actual moon 29.5 day cycle. So if you can live with that the watch is a very nice time piece and does keep excellent time.In most accounts this is a 5-Star watch but I am withholding 1 star because the moon phase is not exact as noted above.

Hard to believe for the money the quality keeps excellent time
