TAG Heuer Grand Carrera Caliber 36 RS Caliper with 43 mm and 15.75 mm case. At just over 190 grams, it is also rather heavy. Its steel construction reminds you that this is a manly instrument that can be used for serious timing tasks.The main feature of the watch is the 1/10th of a second chronograph which comes from the TAG Heuer Caliber 36 movement. Like most two button chronographs, the TAG Heuer Grand Carrera Caliber 36 can be started with a push on the top button. The start button has a solid click feel to it.The long, polished steel, seconds hand will move around the dial in micro-steps while the one-third quadrant at three o’clock tallies the minutes (up to 30) and three quarter quadrant at 6 o’clock tallies the hours (up to 12).When engaged, a second push to the top button stops the chronograph. The second button resets the chronograph along with both the minutes and the hours tallies.Related Replica TAG Heuer Grand Carrera Caliber 36 RS Caliper Chronograph.
What sets this Grand Carrera apart is a simple, but wonderfully useful, and easy to use caliper that allows one to read the 1/10th second measurement right off the dial. Think of the caliper as a physical mechanical “magnifying glass” for the seconds markers.It works as follows, once the chronograph is stopped, you move the caliper using the distinctive crown at 10 o’clock, which is adorned with a red stripe giving the watch an unbalanced yet instrumental feel. That crown moves the caliper back or forth around the dial like an internal bezel.
The caliper is simple, it has 11 digits, marked from 0 to 9 and then 0 again. The first 0 is red and has a special red marker. Using the 10 o’clock crown, one needs to align the caliper’s red marker with the location where the seconds hand stopped. From that point, the 1/10 seconds is indicated by finding the number on the caliper that best aligns with one of the next 10 seconds markers on the dial.The watch measures 43 millimeters with the well protected screwed down crown which is stamped with the TAG Heuer shield armor logo in silver on a black sapphire crystal. The watch’s dial is black with well visible hour markers in polished steel and marked seconds around the dial.The dial is recessed and a second smaller dial where the caliper moves contains markers for 1/5th second between any two second markers. The bezel is also polished steel with a black marked tachymetre that is done discretely, thereby, not distracting the users who may not care to measure speed.
At 9 o’clock is a cutout vertical strip that allows the black and red hands to be seen and move to indicate the current seconds. While interesting and giving the dial an asymmetric feel, it is pretty useless and hard to read since there are no indications of what seconds we are at in a minute…The black hand is shown for the first 40 seconds and the red for the last 20 seconds, thus helping the guessing game, but what I found is that it simply just frustrates me, as it is still too hard to guess what exact second it is at. Unlike most visible casebacks, TAG decided to split this one into two viewing sapphire windows with the remaining steel marked with the TAG Heuer name and logo, model name and number, as well as the unique serial number of the watch.
