That's the good bit. The watch was sent for repair in the original coffin box, but was returned to me in the new stubby box. Not great as that box won't fit the manual and additional strap packaging. CW have sent out a replacement coffin box, but it seems silly to make such a basic error.

More disappointing though is the watch went in with a return note stating that regulation was perfect. At +1spd I was really pleased with what I'd describe as optimal running. Following repair, that superb accuracy seems to have suffered. Given that they are only supposed to have replaced the auto winding mechanism, the watch now runs at -2spd. Beat error is now 0.4ms, up from 0.2. Sure it's still within tolerance, but it's not as good as it was. Is it even the same movement I wonder? Did someone take it upon themselves to dismantle and service it - a poor call if it was running so perfectly.

So while I'm happy that the turnaround was reasonably quick, the customer focus seems to have been a bit lacking. The watch is running within tolerance, but has gone from impressing to disappointing because of the loss of performance.

I know CW can offer great value, but I feel there to be just a bit too much disappointment in the mix. Maybe I've been unlucky? I was looking forward to the release of their next mechanical chronograph, but I'm struggling with the idea of buying another CW and seriously considering cancelling my BC order.

Good to hear they are sending out a coffin box for you.
With regards to the accuracy, I personally feel you may be splitting hairs and doing CW a disservice - the watch will likely have been thrown around a lot during transit, which has likely caused the difference.
I used to work for a vehicle hire firm. It was shocking to witness a courier throwing parcels from the back of one van to the other, when switching over to a new van. Goes to show that the 'Fragile' tape isn't given a second thought by somebody who is simply in a rush to get from A to B as fast as possible.

I buy/sell many CW watches. I wear a new arrival and so long as it is still within reasonable timing by the end of the day, I am generally happy.
I have a few quartz watches if I need to be assured of accuracy every time.
Perhaps, as you hinted, manual/autos aren't the best option if every second counts for you.

I hope you come to live with the accuracy and enjoy wearing your watch

I have a watch with the in house SH21 movement and wanted to fully charge the power reserve. I got to halfway after what felt like about 20 turns and didn't feel comfortable after that. I'm guessing this movement will take it, as after all, that's it's purpose?

Hope this helps.

Obviously, being limited numbers I did a quick internet search, skim read and hit the buy button. Now this evening after digesting today's actions, I delved a little close into the model and am starting to feel alarmed at the reported number of issues. I'm not an experienced watch wearer at all and this is my first ever significant purchase. Fingers crossed mine is up to the task and the QC issues have been ironed out.

So if the timekeeping, which will drift if the Power Reserve (PR) is <3 days is okay, how is the PR itself?

Powering up OK? Holding PR if consistently worn?

At the end of the day CW must have built a fair few thousand products utilising the sh21 and only a handful seem to have had any issues. I will cross my fingers and just try and enjoy my bmf. After all, there is a 5 year warranty and from what I've learned since joing the forum is that cws customer service is pretty good these days.
Thanks for the update
