i obtained several watches from an accomplished watch maker in miod michigan. he is 87 years old and has macular degeneration so his eyes are failing and decided to move out some of his stuff. he has 4 watches that he actually added himself the tourbillion feather to them. they all keep good time and run well. its a feature whitch i read is a gyroscope device that turns about every minute to compensate for gravity. the article alsp states that its the most difficult complication added to a watch. i looked on google and it has much info on it if you would like to look at it. you can see the framing of it in the picturs i took. i took while it was running and you can see the location of the frame has moved from picture to picture. NICE STRONG RUNNING. KEEPS GOOD TIME. MEASURES ABOUT 2-1/4 IN DIA. ON BACK OF CASE IT SAYS WARRANTEED 25 YEARS. ARM & HAMMER SYMBOL. 293407. ON WORKS IT SAYS 2042605,CENTRAL TIME,HEAT & COLD3 ADJTS. 549, MUMA FRECHELIN. THE BACK OF CASE HAS A NICE STEAM ENGINE ON IT. IT LOOKS GOOD BUT HARD TP PHOTOGRAPH IT.
