Description :steel, sapphire crystal, center seconds, luminescence, date, degrees celsius indicator, screw crown, diameter 41 mm, automatic, steel strap, hidden folding closure.True to their motto: ‘Ball Watch – Since 1891, Accuracy Under Adverse Conditions’, the Trainmaster TMT will endure temperature to -40C and has an illuminated thermometer ranging from -35 to 45C. Together with a shock resistance of 5,000Gs; anti-reflective sapphire crystal, screwed-in crown and 37 micro gas tubes for reading time in the dark, the Trainmaster TMT is a watch you won’t want to be without if you are in less-than-friendly weather conditions.
The Ball TMT movement uses a spiral bimetallic thermometer to measure temperature with far more accuracy than temperature modules used in past watches. The outside edge of the spiral is pinned to the frame and a pointer is connected to the centre. As the temperature increases the spiral winds up, deflecting the pointer clockwise.
