I made various short and long measurements during my Caltrain rides from San Jose to San Francisco (and intermediary stations) and back, using the Grand Carrera Caliber 36 along with my Casio Pathfinder and my iPhone 4S. The *non-scientific* results, shown in Tables 1 and 2, indicate that my tag heuer replica watches uk
Grand Carrera Caliber 36 is not only accurate to 1/10th of a second, but it seems to deviate 0.05 seconds to the CASIO Pathfinder for short measurements and 0.15 second from my iPhone 4S clock application digital chronograph for longer measurements.
This is a decent result if you account for the fact that the margin of error of me pushing both the watch and the iPhone start buttons at the same time likely has a margin of error of at least +/- 0.05 second which is in the same order of magnitude as the measured deviations. As Ariel indicated to me, I also realize that there exist electronic machines that will precisely measure the accuracy of your chronograph, however, I don't own one and am not about to invest in one either. Plus, while it took an hour or so of my time to tabulate and gather, it was fun to actually use the chronograph… How many can say that of your chronographs?
As I mentioned, the watch measures 43 millimeters with the well protected screwed down crown which is stamped with the http://www.nalumar.com/cartier-replica-uk.html
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. The movement also does not hack so this cut has an always moving hand, I guess it tells you the watch is functioning.
The accuracy of the chronograph is in great part due to the El Primero-based movement which is a C.O.S.C. certified movement that beats at 36,000 bph. The beautiful movement can be seen from the sapphire window on the back.
Unlike most visible casebacks, TAG decided to split this one into two viewing sapphire windows with the remaining steel marked with the hublot replica watches uk
name and logo, model name and number, as well as the unique serial number of the watch.
The self-winding rotor is decorated with the TAG Heuer name and logo and cut open to better show the movement which is itself decorated with rubies, blue steel screws, and brass gears. The whole thing is quite impressive and accentuates the feel of a solid instrument.
While the watch is heavy (0.43 lbs) and large, it actually wears small and seats comfortably on my 7.5 inch wrist. This is due to the steel bracelet whose lugs start of at 22 mm and narrow down at the deployment clasp that contains two small pushers making a satisfying click on open and on close. The small buckle has an engraved, flattened, TAG Heuer shield armor logo. It is small but easily visible thus allowing one to quickly see where to detach the strap.
The steel strap alternates with polished and brushed links that could not work better with the polished bezel and the hour markers. That combination gives the watch a slight shiny appearance that, while not ostentatious, makes it noticeable from far.
While this watch is easily the most accurate mechanical chronograph that I own and its speedy looks makes one want to be part of a race, it has a few minor negatives. Besides the useless seconds strip on the dial, this watch is not meant to be used at night.
The dial is simply not visible at night. There is a thin strip of Super-LumiNova application on the hours and on the minutes hands, but the hands are hardly viewable but for a few minutes after a charge.
TAG Heuer makes four versions of the Grand Carrera Caliber 36 RS Caliper. The stainless steel version reference CAV5115.BA0902, reviewed here, sells for a manufacturer suggested price of $9,500, a steel with rubber band which is reference CAV5115.FT6019, and a black PVD titanium with black leather or black rubber strap which are references CAV5185.FC6237 and CAV5185.FT6020.
The black edition is slightly larger and has a higher price at $10,500, but not all are not limited editions, while they do have unique serial numbers. All the models are water resistant to 100 meters.
All models have small red accents on the dial to indicate the caliper marker, the minutes and hours tally, as well the caliper crown. Overall I am quite satisfied with the TAG Heuer Grand Carrera Caliber 36 RS Caliper Chronograph. It's a super accurate chronograph and the innovative (even though it borrows from a very classic concept) 1/10th of a second caliper readout works brilliantly and adds to the overall look and feel of speed and racing that this model and the TAG Heuer brand stand for.
