Sorry if this has been brought up before, but are Doxa watches safe to use in an ultrasonic cleaner?
I recently noticed that my Sharkhunter gets pretty greased up (especially in the band) so I happened upon an ultrasonic cleaner in the store.
If it's not safe to use, then I won't bother... but I would love to be able to clean the Sharkhunter once a month (or more) if it was safe and only took a few minutes.
If you use one to clean your Doxa, can you recommend a brand or model? It looks like a lot of the cheaper cleaners are not well reviewed. I'd pay for a quality cleaner.
Also, do you use any kind of cleaning solution as some suggest?
