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 practice, Glashütte Original presented the Senator Chronometer watch in 2009. Not exclusively does the Senator Chronometer inspire the design of noteworthy marine chronometers however it was additionally the main Glashütte Original watch to display official chronometer status. As a beneficiary to the glad practice of marine chronometers worked in Glashütte, accuracy is the situation and the shrewd stop-second/reset system is intended for hyper-exactness time setting. The Senator Chronometer was returned to in 2016 in this 42mm white gold and dim blue dial rendition ( see the more established form here ) demonstrating that noteworthy plans can rise above time and take a gander quiet – and surprisingly exquisite –  in the 21st century.

Marine Chronometers from Glashütte

Determining longitude was indispensable for nautical countries and observatories in Paris (1667) and Greenwich (1675) were set up to take care of the issue of setting up the specific situation of a boat adrift. It was not until British woodworker turned-clockmaker John Harrison idealized 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 unsafe. With Dresden’s pleased custom of logical perception watches, it was not really astounding that the establishing fathers of Glashütte’s watchmaking industry in the 19th century were propelled to deliver German accuracy timekeeping instruments on a more mechanical 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 unmistakable quality 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 critical 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 created around 5,500 quartz marine chronometers and around 8,000 mechanical marine chronometers. (As to 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 noteworthy Glashütte-made marine chronometers were ‘recuperated’ and reestablished by Glashütte Original. To praise the fortunate find, in 2010 Glashütte Original chose to make a gatherer’s bundle matching the original and reestablished marine chronometer in an oak case alongside a restricted release platinum model of the Senator Chronometer. The similitudes between the ‘recuperated’ Glashütte marine chronometers and the Glashütte Original Senator Chronometer – barring the chronologically misguided Panorama Date window – stress the authentic ties that Glashütte Original has vindicated since it was procured by the Swatch Group in 2000.

2016 variant 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 an interesting matte blue dial with a grainy surface that drastically changes the character of the watch. It actually notices the design 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 at present flooded with blue watch dials yet not many of them are as recognized or as exquisite as this specific matte grayish-blue tone that GO’s dial producers in Pforzheim have accomplished. Utilizing a blue polish base that is grained for extra surface, the markings on the dial are engraved and afterward excited in silver. Silver and dull blue are one of the sharpest shading combinations out there and the watch looks fresh and amazingly rich. Compared to the other models with white dials that ooze a feeling of old-world horology, the blue dial appears to be totally contemporary and fresh.

Another more unpretentious change can be seen on the bezel. Upgraded in 2016, the bezel loses its thicker extents and receives a more slender edge, similar to that found on the Senator Chronometer Regulator. It probably won’t appear to be serious, however the slimmer bezel is more exquisite and implies that the dial is bigger. Another minuscule change that goes far in permitting the watch to breathe is the consolidation old style hauls (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 favorable position in light of the fact that the case can be polished.

The worldview of a marine chronometer dial

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

The two sub-dials are marginally recessed adding more profundity to the dial and the force hold marker skirts around the Roman numeral XII. This dazzling point of interest implies that the Roman XII remaining parts flawless and on similar level as the other numerals on the dial and has not been hurled off at the base like the numerals V and VII. To set the time or the date, a convenient day/night work is situated inside the force save 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 pivot of the hands following the bend of the counter.

The unmistakable Panorama Date show, which hops ahead accurately at 12 PM, is set at 3 o’clock and highlights a blue foundation to coordinate the dial. The mystery of its remarkable readability 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 edge and soft, adjusted edges. The differentiation of the matte blue foundation, the silver markings and the exquisite white gold pear-formed hands scheme to make an astoundingly neat 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 official chronometer status set the Senator Chronometer in a classification all its own. The imaginative 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. All the while 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. In other words, the watch can be set to the specific moment and second, as befits a “Made-in-Germany” chronometer. Another detail that talks about the accuracy idea of this watch is the little snap you can feel for consistently when turning the crown.

The sapphire precious stone caseback uncovers the lovely manual-winding type 58-01, complete with the exemplary three-quarter plate with Glashütte stripes, the hand-engraved equilibrium rooster, 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 gloat official chronometer status: the Senator Chronometer and the Senator Chronometer Regulator. The part of the German Calibration Service (DKD) that attempts the chronometry tests is situated in Glashütte in the reestablished galactic 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 – thus the stop-seconds/reset mechanism.


With its 42mm distance across and case stature of 12.47mm, the watch is really a couple of millimeters thicker than the pre-2016 models. Nonetheless, interestingly, the upgraded 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 strength of the notable watches. The blue tone of the dial is in its very own association; it is refined, rich and calm and the differentiating silver markings make it prominently clear. I’m an enthusiast 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 croc leather 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.
