Congrats on the Seamaster Joss! :thumbup: I've got a Seamaster Chronograph myself, plus my (almost) EDC Rolex Explorer.
I wanted to chime in on accuracy in mechanical watches, because its clear that most don't understand what they're seeing or hearing about. -A lot of the same old misinterpreted anecdotal stuff.
Take Rolex, for example: there are
many high-end mechanicals that are more expensive than Rolex. Rolex is not considered haute horologie. There are none however, that are more accurate
as a brand.
In mechanical watches there is the COSC, Swiss Chronometer Certification. They set the standard for accuracy, and it's an old one, pretty easily met by today's mechanicals, certified or not. When a movement earns a Chronometer certificate it means that the movement (outside the watch) performed to a standard that works out (through a convoluted route) as no more than +6 seconds to -4 seconds a day, over several positions, temperatures and over a number of days.
That's it. Any Chronometer should run within Chronometer specs. You may find a Rolex, or an Omega, or an IWC that runs spot on. You may find any of them that runs +6 seconds a day, or -3. They're all within spec, and really, +6 seconds a day every day, is better than +1 today, -3 tomorrow, because consistency is the goal. -You might even find an Omega that runs +1 second a month, but I promise "Omegas" do not, and certainly nor do Rolex, nor IWC and so on
as a brand.
The point is if you hear someone say, "Rolex aren't that accurate." that's simply false. Rolex (in the past as proof of quality, these days more as a marketing tool) certifies more Chronometers than anyone. That means they sell more watches guaranteed to run within a certain spec than anyone.
