Here is what I did a while back and it doesn't loose a second. This is about a Speedo and a the Clock, keep that in mind:
Some feedback for all of you thinking of sending your Speedo to North Hollywood Speedo or your Bavaria clock. I was having reservations after I heard there were new owners etc. and some people had some bad experiences. I heard some good ones too so I eventually gave it a shot after trying to repair both with a friend and it didn't work out as planned.
I am happy to report, both turned out great and turn around time was minimal. It was not cheap, but within reason (I guess). The Speedo needed parts, so it cost $138.75 + $46.25 "assorted parts" (that's all they said). So $185.00 speedo. Clock they do not repair anymore, but they will put a quartz back on it. I wanted that anyways, supposedly they come out of a Porsche 993 and that explains the cost. For all I know it came out of a VW. But I will say this, it runs like a charm. Right on the money. This was the hard part - $288.75 plus $96.25 for Parts = $385.00. Shipping $21.74 + 12.47 Sales tax.......Total bill: $604.21 ouch...... but all done. Checked speedo with Waze App and various radar speed traps around town and seems to be working great. I love having the clock work like a charm, it's the little things sometimes that make this all worth it. I have no affiliation with NHS at all, just an onsite e9coupe.com Yelp review...LOL Oh, and be very careful replacing the clock, don't force it in, it can be tricky, have some patience and it will get back in place.
