I have been generally cleaning watch cases in my ultrasonic in my watch cleaning and rinsing solutions with great success followed by either gentle polishing or buffing with Simichrome.

With the recent purchase for my wife this Bulova, I am now wondering how best to clean enamelled cases. Can they withstand the ultrasonic? What is the best way to polish?

Your thoughts are appreciated.

Hi Patrick:

I believe I asked a similar question here myself years ago, and if I recall, the advice was to NOT put the enamel in the ultrasonic as any bits or chips that are compromised or potentially loose may be jostled out. I clean pieces like this by soaking them in a half water/half Mr. Clean solution, and then I swab them down with a q-tip soaked in the same solution.

Regarding the Simichrome, I was told that the enamel is hard enough to withstand hand buffing with that sort of polishing compound.

Please wait for others to weigh in with their experiences, though, as I do not want to be responsible for any damage to your lovely watch!

+1...I agree with Retro. I would not put it in an ultrasonic. I also use a warm solution of Mr. Clean and water (which was what was used in the jewelers ultrasonic where I used to work - years ago). I would think Simichrome would be fine on the enamel - but if you are concerned just limit the pressure you use on the non-metal surfaces.

BTW - my wife has a very similar Westfield. Nice looking watch.

Thanks for the advice, appreciate you both weighing in. Wouldn't want to ruin my wife's new watch! As a hobbiest I'm NOT doing the COA on that watch so it's out to a professional, too precious. I will however look after the case cleaning and new crystal instal.

I do recall going into a jeweller and asked about a cleaning solution they had on the counter - it was a solution with Mr. Clean!

I use ammonia and water (25/75 ratio) submerge for 15 minutes then use a kids worn tooth brush and brush softly around around edges. Then put into water for a minute. Dry it and the new use a Cape cod cloth to polish it up the a sylvet cloth to polish.
