Glashütte Original Senator Chronometer (Incl. Glashütte’s History of Marine Chronometers)

Marine chronometers were a staple of Glashütte’s watchmaking industry for longer than a century. To respect this custom, Glashütte Original presented the Senator Chronometer watch in 2009. Not exclusively does the Senator Chronometer summon the design of noteworthy marine chronometers yet it was likewise the main Glashütte Original watch to display official chronometer status. As a beneficiary to the glad custom of marine chronometers worked in Glashütte, accuracy is the situation and the shrewd stop-second/reset instrument is intended for hyper-exactness time setting. The Senator Chronometer was returned to in 2016 in this 42mm white gold and dull blue dial form ( see the more established form here ) demonstrating that noteworthy plans can rise above time and take a gander quiet – and strikingly rich –  in the 21st century.

Marine Chronometers from Glashütte

Determining longitude was crucial for nautical countries and observatories in Paris (1667) and Greenwich (1675) were set up to tackle the issue of building up the specific situation of a boat adrift. It was not until British woodworker turned-clockmaker John Harrison culminated his marine chronometer (bringing about the H4 model of 1761 that at last won the Board of Longitude’s Prize cash) that route adrift turned out to be more exact and less risky. With Dresden’s glad custom of logical perception watches, it was not really astounding that the establishing fathers of Glashütte’s watchmaking industry in the 19th century were enlivened to create German accuracy timekeeping instruments on a more modern scale.

During a discussion given at the Horological Society of New York in 2017, visitor speaker Ulrike Kranz (corporate communications for Glashütte Original) underlined the conspicuousness Glashütte achieved in the creation of marine chronometers. “With the establishing of the German Empire in 1871 and developing interest in worldwide exchange, the German Navy turned out to be increasingly more essential to the German government. To lessen dependence on English imports (counting the notable English marine chronometers), huge help was given to support the creation of marine chronometers in Germany. In 1886 the principal marine chronometers from Glashütte were shipped off the German Naval Observatory in Hamburg for testing.

The creation of marine chronometers in Glashuette began in the year 1886 and proceeded in the VEB Glashütter Uhrenbetriebe (“GUB”) from 1951 on. Between the years 1886 and 1978 Mechanical marine chronometers were delivered and between the years 1974 and 1992 additionally Quartz marine chronometers were created. Altogether, the GUB delivered around 5,500 quartz marine chronometers and around 8,000 mechanical marine chronometers. (Concerning mechanical marine chronometers there are chronic numbers beginning with number 1 and the creation halted with the number 13190 in the year 1978.)

A lucky find

Just in front of the kickoff of the German Watch Museum in Glashütte (helped to establish by the town of Glashütte and Glashütter Uhrenbetrieb GmbH/Glashütte Original 2008), thirteen memorable Glashütte-made marine chronometers were ‘recuperated’ and reestablished by Glashütte Original. To commend the fortunate find, in 2010 Glashütte Original chose to make a gatherer’s bundle blending the original and reestablished marine chronometer in an oak case alongside a restricted version platinum model of the Senator Chronometer. The similitudes between the ‘recuperated’ Glashütte marine chronometers and the Glashütte Original Senator Chronometer – barring the chronologically erroneous Panorama Date window – accentuate the recorded ties that Glashütte Original has vindicated since it was gained by the Swatch Group in 2000.

2016 adaptation versus past Senator Chronometers

To date, the Senator Chronometer has showed up in non-restricted releases in 42mm rose gold and white gold cases with white dials and blued hands. The 42mm white gold model we are reviewing today was delivered in 2016 and has a special matte blue dial with a grainy surface that drastically changes the character of the watch. It actually notices the format of a marine chronometer, however the shade of blue and the surface accomplished on the dial loan it a totally different presence.

The market is as of now flooded with blue watch dials yet not many of them are as recognized or as rich as this specific matte grayish-blue tone that GO’s dial creators in Pforzheim have accomplished. Utilizing a blue finish base that is grained for extra surface, the markings on the dial are engraved and afterward aroused in silver. Silver and dim blue are one of the most astute shading combinations out there and the watch looks fresh and incredibly rich. Compared to different models with white dials that radiate a feeling of old-world horology, the blue dial appears to be altogether contemporary and fresh.

Another more unobtrusive change can be seen on the bezel. Overhauled in 2016, the bezel loses its thicker extents and embraces a more slender edge, similar to that found on the Senator Chronometer Regulator. It probably won’t appear to be serious, yet the slimmer bezel is more rich and implies that the dial is bigger. Another minuscule change that goes far in permitting the watch to inhale is the joining traditional carries (rather than interagted drags) making a space between the lash and the watch case. Likewise with all the white gold utilized by Glashütte Original, the higher extent of palladium in its content outcomes in a lighter shading that needn’t bother with rhodium plating: a preferred position in light of the fact that the case can be polished.

The worldview of a marine chronometer dial

Original marine chronometers had an unmistakable look and would in general component a little seconds sub-dial at 6 o’clock, enormous Roman hour numerals, a railroad section ring for the minutes, pear-formed hands, and a more modest sub-dial at 12 o’clock to demonstrate the force left in the barrel. The Senator Chronometer is a loyal generation of the design of a run of the mill marine chronometer dial – barring the enormous Panorama Date window, of course.

The two sub-dials are marginally recessed adding more profundity to the dial and the force hold pointer skirts around the Roman numeral XII. This beautiful detail implies that the Roman XII remaining parts unblemished and on similar level as different numerals on the dial and has not been heaved off at the base like the numerals V and VII. To set the time or the date, a helpful day/night work is situated inside the force hold counter changing at 6 am and 6 pm from white to blue, while the exceedingly significant status of the watch as a chronometer is engraved simply over the hub of the hands following the bend of the counter.

The unmistakable Panorama Date show, which bounces ahead exactly at 12 PM, is put at 3 o’clock and highlights a blue foundation to coordinate the dial. The mystery of its remarkable decipherability lies in the mounting of two concentric showcase circles on a similar level, which makes it conceivable to introduce the two date numerals without the requirement for a focal detachment bar. Rather than the rectangular window that outlines the complication on Pano watches, the date window on the Senator Chronometer includes a twofold sloped casing and delicate, adjusted edges. The differentiation of the matte blue foundation, the silver markings and the exquisite white gold pear-formed hands plan to make an outstandingly clear dial.

Calibre 58-01 Chronometer

This probably won’t seem, by all accounts, to be the most complicated of Glashütte Original watches, yet the activity beneath deck and its authority chronometer status set the Senator Chronometer in a classification all its own. The creative stop-seconds/reset component with minute detent makes it a lot simpler to synchronize the moment and seconds hands when setting the time. At the point when the crown is pulled, the time show is halted and the seconds hand dashes back to nothing and stays there. At the same time the moment hand advances to the following entire moment. At the point when the crown is gone to set the time, the moment hand stops on the entire moment ensuring the right connection between the minutes and seconds showed. As such, the watch can be set to the specific moment and second, as befits a “Made-in-Germany” chronometer. Another detail that talks about the exactness idea of this watch is the small snap you can feel for consistently when turning the crown.

The sapphire gem caseback uncovers the wonderful manual-winding type 58-01, complete with the exemplary three-quarter plate with Glashütte stripes, the hand-engraved equilibrium cockerel, screw-mounted gold chatons, blued screws, electrifies surfaces, slanted edges, perlage on the base plate, the swan-neck fine change and a planetary stuff train for the force save show. Wavering at 28,800vph, the running time is of 44 hours and 40 minutes.

Only two watches from Glashütte Original brag authority chronometer status: the Senator Chronometer and the Senator Chronometer Regulator. The part of the German Calibration Service (DKD) that embraces the chronometry tests is situated in Glashütte in the reestablished cosmic observatory where tests are directed over a time of 15 days. Not at all like the Swiss chronometer office COSC, which tests uncased developments, DKD tests the cased watches and necessitates that each chronometer can be set to the second – subsequently the stop-seconds/reset mechanism.


With its 42mm breadth and case stature of 12.47mm, the watch is really a couple of millimeters thicker than the pre-2016 models. Nonetheless, interestingly, the overhauled bezel and the combination of a dim blue dial and white gold make the watch look more modest and slimmer than it is on paper. It is after every one of the a little marine chronometer and something more modest would not have caught the toughness of the memorable watches. The blue tone of the dial is in its very own alliance; it is refined, rich and calm and the differentiating silver markings make it prominently intelligible. I’m a fanatic of the Panorama Date window and despite the fact that it very well may be a time misplacement given the marine chronometer styling of the watch, it is a significant piece of Glashütte Original’s identity.

The Senator Chronometer in white gold comes with an attractive blue gator cowhide tie. The model we reviewed for this article comes with a white gold collapsing catch and retails for EUR 27,200 despite the fact that there is additionally the choice of a white gold pin clasp EUR 25,100.
