Actually, I updated that photo tonight. I replaced #6 with my latest compass and removed the Japanese liquid filled present day Randall compass. It finally formed a bubble after about 5 years.I know this photo you posted, I have that photo saved on my computer since times ago.
I don't doubt that these companies might have made mini dry compasses in the past. My comment in post #2968 still stands. There is only one mini (1.5 cm or less) dry high quality compass being made today that I am aware of. If there are others being made today, I would love to see them.As I mentioned, the companys I told you made dry and liquid filled compasses.
I have read this is not a good idea because dry compasses use higher quality (harder) jewel bearings that can withstand years of dial rotation. Liquid filled compasses use lower quality (softer) bearings. The liquid has two functions - 1) to slow down/steady the dial and 2) to soften the dial rotation by lubricating the bearing. According to compass manufacturers, the bearing will eventually wear out if the liquid is removed.Anyway, Is easy and simple to take of the liquid of liquid filled compasses.
