Buloloy Mainspring

How to add images to myBulova.com forums & comments

There is little that I have found regarding how (and with what oil) to properly lubricate a mainspring. There is also info that alludes to certain mainsprings that are coated and do not require oiling less they may eventually bind.

I have just installed an NOS Buloloy mainspring from an Insertopak intona barrel for a 10BC. What is the proper oiling procedure for this mainspring? What IS the correct oil to use?

Thanks in advance!

I use a medium weight watch oil and place just the tineyest amount on the spring from center to outside edge while it is in the barrel. This has worked for me for many years.

Is the watch oil you use Moebius 9020?
