A terrific question! Thanks very much for presenting . . .

. . . it, Chris, and also to Jeff and Michael for their contributions to this discussion.

My understanding of the design for the cal 58 movement is that the correlation between minute and seconds hands is maintained while the drive train is engaged, and not just when setting time. The visual display of time should retain the correct relationship between all hands under dynamic conditions.

I agree with Jeff and Michael that this is a significant and meaningful distinction, which in my opinion renders the Senator Chronometer a special place in the pantheon of modern wristwatches. The anecdotal evidence from both Michael and my brief experience in 2010 suggests the cal 58 is capable of a very high level of accuracy in absolute terms. The synchronization of all three hands does not in and of itself contribute to mechanical stability, but does lend consistency in rate measurement. This result is, in my opinion, meaningful.

It's the enhanced interface between watch and wearer that distinguishes the SC from other designs; the relative truthfulness of its read-out is the icing on the cake.

Thanks, all, for a truly enlightening thread!

Cordially,

GO Senator chronometer

So as we were talking about this fine chronometer (my friend is in love with it), we stumbled upon a debate that have lasted us forever but we haven't agreed on anything. For me, it's not a matter of opinion so would like to seek advice here. First of all...

So the debate continues :)

So my point is (trying to keep this as short as possible): 1) For me, "accuracy" not only confines to the actual time-keeping, but also to how the time is presented 2) Since with the SC's function for one to set time with stopped second and stepped minute...

Time keeping accuracy and hand alignment accuracy...

The SC certainly has both.

As an owner let me share my thoughts.

And BTW I am working on a collaborative review of this exceptional piece, and we will delve into this further. My fascination of "chronometers" started will Ulysse Nardin's ship chronometers. I learned how they were used to navigate the seas, and how para...

Thanks Michael

for taking your time to post, and it is exactly what I have in mind. As you said (and so have I) - the stop second + minute-jumping adjustment in itself does not increase the accuracy of the timekeeping of the watch, but it certainly enhances the accuracy...

And a photo...

By: MichaelC : February 27th, 2012-08:14

You can see here the seconds are at 20 and the minute hand is not quite halfway between the adjacent minute marks. When I post the review I will capture it at 0....

beauty.....

I guess I can do with the date!!

Problem solve if you have the right definition of accuracy.

By: TdotBean : February 27th, 2012-18:53

Accuracy of time keeping: stop seconds/reset mechanism doesn't help in that. Accurarcy of time displaying: stop seconds/reset mechanism does help. Now it will be foolish to measure accuracy without proper displaying it, right? I guess we can narrow down a...

Correct!!

By: kelsiph : February 27th, 2012-19:05

You have nailed it Tyler! We went on a bit more and found it looping around the definition. And in the end, the SC is great in every sense, you are absolutely correct. It's not so much the definition of accuracy but a matter of differentiating accuracy an...

Well ... I think you misunderstood me.

By: TdotBean : February 27th, 2012-19:37

As you wrote "This piece has a stop seconds/reset mechanism and a precise minute synchronizing and I said that this is a neat function and that it helps with the setting of the watch precisely but only that. It doesn't help with the accuracy of the watch....

A terrific question! Thanks very much for presenting . . .
