Ball watches are of a pretty rare kind, as the man behind the brand that is located in Neuchâtel, Switzerland, is Webster Clay Ball, a former citizen of Cleveland. Since its inception in 1891, Ball has made itself a name for robustness, accuracy and decisive readability, which this commemorative piece is no exception to. The Trainmaster Celcius commemorates the anniversary of Anders Celsius birthday, and comes with a clean-cut 41mm stainless steel case. The inside provides its collector a Ball automatic in-house caliber 9018 featuring a Thermometric gauge and a power reserve of 42 hours.
