The new Ball for BMW TMT Chronometer watch incorporates the mechanical thermometer seen on some other Ball timepieces while remaining very consistent within the Ball for BMW family. It also shows in various ways how Ball is responding to the details and specs enthusiasts want with a very cool looking piece that’ll please fans.
Ball’s Temperature Measurement technology (TMT) refers to a proprietary module added to, we believe, the ETA 2892 automatic movement for this watch, now called the BALL RR1601-C. Ball explains that its system which uses a “spiral bimetallic thermometer” is more accurate than thermometers on watches that came before it, and claims to be able to measure the environment’s temperature from –31°F to 113°F (–35°C to 45°C), with an accuracy of 97%, or a “precision range of within +10°F.” Ball notes the engineering challenge of keeping the movement 5.1mm thick with the addition of the module’s temperature-measuring coil. Unfortunately, it doesn’t seem like this part of the movement is viewable through the display caseback, though it makes sense that you would want it closer to the dial and away from the wrist.
We have seen this technology (and layout, including the date window at 1 o’clock), for instance, in the Ball Trainmaster Kelvin watch (reviewed here by Patrick Kansa). Temperature always seemed like a cool thing to be able to reference from one’s wrist to me, but I have wondered how it might be affected by body heat. It should at least be fun to see the hand move as you go inside or outside, as well as to point to your wrist as you complain about the weather.
Anti-reflective sapphire crystal up front, of course, and the caseback is also sapphire, which seems only appropriate for viewing a certified chronometer movement. For durability, the Ball for BMW TMT Chronometer Ball also includes the brand’s patented anti-shock “Amortiser” system and is antimagnetic to 4,800A/m. It would hardly be a Ball watch without the use of glowing tritium tubes they are known for – here, 14 of them in use. That’s a lot of enthusiasts’ boxes checked.
