I'm having some analog clock weirdness going on. Sometimes it will lose a bunch of time. Then the next time I get in the car it has magically corrected itself. Is this common?

There's a setting in the Vehicle menu that disables the automatic bit, but I'm not sure why the clock would stop for periods. Sounds like you need a new clock.

Are you saying that the clock can be changed? Then can I assume that a c200 can have the analogue clock of the c63? that gorgeous IWC clock?

Yeah, any part can be swapped out, but MB isn't going to do that swap under warranty. Maybe you could cover the difference though for the up charge. A vendor on EBay has them for $426. As long as your car has an existing clock, should be plug and play.

I wondered how reliable those clocks would be. But I thought they'd last longer than this. I haven't even had the car a month! At least this is the only problem I've had. Everything else has been working perfectly. I thought the head up display had quit working until I found the switch for it and turned it back on

There have been very few problems reported with the clock. I remember reading a post about a year ago from someone who had a similar issue, but that's about it. It should be a simple warranty replacement.

honestly i'm not surprised.

this is the third benz in my family. The first 2 had a lot of minor electrical issues.
the most major issue was on the R350 which the steering fluid reservoir froze and cracked. Car lost power steering on a busy highway.

i'm so far knocking on wood on my C class. no issues so far

Couple posts in the W212 E class section mentioning this, mine included. For me, it happens when the car sits outside when it's warm out, the analog clock falls behind. Other posts state dealer will replace under warranty. I'll mention it at next service.

That seems to be exactly when it happens. It always seems to be right when I leave in the morning. But when I leave from work in the afternoon I notice it has lost time sometimes. I'll wait until the first service and have them fix it then. In the meantime it's liable to not work very well if the problem is heat related. The brutal Phoenix summer is right around the corner

Isn't the clock digital, tied to the car's electronics? Or is it stand-alone like a traditional clock with it's own internal mechanism? Trying to understand how it would lose time.

RobbieAZ

I assume it's tied into the car's electronics since it corrects itself.

First you should check your battery. Electronics in car when recognize low voltage on battery turn off elements which are not important to save energy (it is described somewhere in instruction). So in this situation it can turn off clock.
Second option - broken clock it not working correctly (loosing time). When you turn car on it check time (via GPS) and make correction.
