Here is a recent picture that Eddie posted of the trim (aftermarket) that houses the clock so you can see where the mounting tabs are located.




Here are pictures of the Lexus clock from a 2013 GS 350.










It appears the clock's related circuitry is in a sealed case mounted directly behind the clock face. I don't know how difficult it may be to get into the case in order to test/repair/replace component(s) if you were so inclined, but it looks like the black part directly behind the clock bezel just unclips which likely gives access to the crystal oscillator and other related circuitry. I seriously doubt there is an adjustment that can be tweaked...

It looks like a new Lexus Clock P/N#83910-30620 (for 2013 & 2014) is $345.00, but discounted it can be bought for around $260. I found a new clock on eBay for $160. I don't know how much a used clock could be bought for from a junk yard...

Hmm, won't be spending $160 on a clock.

A controlled experiment was conducted: I rolled it back a full 24 hours and set it correctly. Then checked it afterf 24 hours showed a gain of 30 minutes. That's 1.25 seconds fast per minute. I'm running it back another 24 hours and will measure again to see if it is making any progress in retarding it.

I'm still baffled as to why it worked perfectly for a year and then turned into Speedy Gonzales overnight, doing a minute in 58.75 seconds?

Two full days of running it back 24 hours and it is still running almost exactly 30 minutes per 24 hours fast.

Oddly, I did lap times for 8 minutes and the average minute on the dial was 59.8 seconds.

When I run it back I hear a strange noise as the minute hand makes it backwards motion.

I'm going to setup a time lapse shot of it overnight to be sure that it isn't doing something odd.

You are to adjust the clock 'backward' 23 hours and 59 minutes (don't ask why because I have no clue why), not a full 24 hours.

Just an idea, but the watch being used to compare could be off?

I'm pretty sure it has nothing to do with the tires

Apparently, this is a bigger problem just my isolated incident. Lexus Clock Thread

The reference lap timer is my phone. It is pretty accurate.

I know the tires have nothing to do with it but I had tires put on that Friday morning. The following Saturday morning it was 30 minutes fast. Not related but knowing it is 30 minutes off per day tells me it started the day i dropped it off for tires. It was tongue in cheek humor to start but apparently nobody really gets humor here. It would be like waxing the front bumper caused the rear axle to leak. Other than being on the same car, they are unrelated and only coincidentally happened at the same time.

Now, have I made it clear it was a joke and not a serious question about how tires affect the clock?

I find analog with no numbers too hard to read while driving so I don’t even use it. I think mine was 3 hours off for the first 3 months of owning the car.

Knucklebus

Well, nothing so far has helped. It runs 30 minutes per 24 hours fast. Period. Once the spin of the planet increases I'm all set.

Did you see this old post that just reappeared yesterday? https://www.clublexus.com/forums/gs-...-too-fast.html

No but if there is TSB it is far from the isolated issue some would have you believe. Does a TSB have any impact on an out-of-warranty unit? I'm not putting $200 into a cheesy, trouble-prone clock.

TSBs don't apply if you are out of the warranty period, unless specifically stated in the TSB.

Knucklebus

And nobody to date has produced a TSB number to reference.

I'll just stick this over it.

Better than pumping hundreds of dollars into the factory clock that seems to randomly have this issue.

2013 4GSh no clock issue I'd replace with OEM otherwise it will look cheap or out of place. The negative reviews talk about worse issues than your clock. Also you would have tho take the clock apart to adjust the time for daylight saving.

Knucklebus

I can take it apart twice a year for $200.
