Sophisticated technology.
The Senator Chronometer is powered by our Calibre 58-01, a manual winding movement. Among its features is a refined stop-seconds mechanism: when the crown is pulled out, the time display stops and the seconds hand is reset to zero and held in that positio...
It’s a remarkable watch indeed.
Where is it chronometer-certified at, and what are their criteria for testing chronometers?
Some info.
Every Senator Chronometer is individually tested in the astronomical observatory of Glashütte. Find this info: This German standard is similar to ISO 3159 that forms the basis for COSC certification . Watches are tested for compliance with DIN 8319 at Gla...
Much appreciated.
It sounds more exhaustive than COSC, if my initial recollection doesn’t fail me. Love German engineering (and quality control) 👌🏿👆🏿👍🏿💪🏿
The most notable difference
between Swiss and German Chronometer procedures might be that in Switzerland the movements are tested before they are encased while in Germany the complete watch is tested. The latter eliminating the risk that the already tested accuracy of the movement m...
That is true for COSC, but not METAS, Qualite Fleurier etc.
Personally, a watch is only a Chronometer if it’s tested as a final product.
Well stated as always.
For the record, my GO Chronometer is near perfect. So it is my Tudor METAS tested ceramic Black Bay. A joy to have some accurate mechanical timepieces.
I love the blue dial in these computer art photos, but have found it falls flat in person.
I have seen it live on multiple occasions, and I was not inspired by it.
No it does not. But it incorporates a precise setting feauture.
Much has been written about it. Basically, when the crown is pulled, the seconds hand resets to 0. As you adjust the minute hand, it ratchets to each minute marker. Push the crown back in, the motor comes alive and the seconds and minutes hand are perfect...
Ahhh… this makes sense. Thanks fir the clarity. I too have struggled with where to point the hand while setting the time…
I always use the backlash approach; but that doesn’t solve the actual location
In my days with machining, one appreciates that when two gears interact there is play/space gap between the teeth of the two gears.
“Backlash approach”….so when I am setting the time (for example 1:30) I will move the minute hand to “6”, but when I finally set the minute hand (regardless if I came from clockwise or counterclockwise) I will always come from the “past” and move the minu...
