The UN-118 was first introduced in an enamel dial special version at Baselworld in 2012. I have the same watch, on a bracelet, and it is the most accurate mechanical watch I own, consistently running within 15 seconds a MONTH. A super watch and a smashing deal in the secondary market. No problem wit

Wait, that didn’t come out as I expected... —Rick

The clutch wheel has ellipsoidal teeth because they are constantly engaged with the wheel on the back of the fourth wheel shaft.

on the recently replaced Caliber 12 Monaco. The modern Caliber 12 is a worthy descendent of the original Caliber 12. The Buren tractor in the original was chosen for its thinness, and that applies to the 2892/SW300 tractor in the 12. Both have the same (or nearly so) Dubois-Depraz module. Unlike mos

And that’s the problem with the Longines re-editions—they are pulling up the aesthetics, but not the great Longines movements of the past.

So, if everyone wore them, it would greatly reduce the large virus load projected by coughing by those who don’t yet realize they are sick. Then, even limited effectiveness of the mask at preventing one from getting the virus stands a better chance of being enough. Our friends in Singapore get this,

My father was given a Hamilton 782 pocket watch by his college buddies in 1949—he commanded their ROTC company. I own a Hamilton 992 railroad watch (16 size pocket watch) from 1946. But my father in law gave my wife the (tiny) Bulova His Excellency wristwatch given to him by a lady friend in 1950. I

But Ball didn’t, as I recall, make his own watches. He used watches made by others and applied his accuracy improvements. In response to a problem of train crashes, he became a consultant to the railroad industry and established the standard for railroad watches in the USA: my fuzzy memory says 15 s

At least for sheer interest. But my favorite complication is the one I happen to be wearing that day. —Rick
