That's a good question

For clocks, the trick is to look for any shafts that are square. This is so that you can have a good "grip" on the shaft to turn it (i.e. transmit high torque), to wind the barrel.

Also, within the same area you will notice gears are made of steel, not brass. Steel is a high strength material which can safely transmit the high torque needed to wind the barrel, which brass lacks.

In this case, The winding arbor is visible around 4 o'clock. The description of the clock however, says winding is "remote on bezel". My guess is that by turning the bezel, it engages an internal ring gear that turns this arbor. I can't tell from the photos alone.

EDIT: I just watched a video, where the entire bezel can be turned to reveal a hole/cutout, which you can then slot in the winding crank to wind the bezel or set the time, etc.

On the reverse, you can see how the gears link towards the fusee - which is the cone-shaped drum that acts as the constant force device. Now, keen observers would notice something unique - there are actually two fusee and chains in this clock! If I had to guess, this is equivalent to the idea of a wristwatch having mainsprings in parallel.

Perpetual Calendar, Equation of Time, Moon Phase, Zodiac, Power Reserve, 30 day autonomy, etc. in a wood box for your desk (on your megayacht)? You would have a Thomas Mercer Observatory Marine Chronometer . Who thinks of these things, and further, actual...

I'll be "that guy" and share some comments

At this level of luxury (or honestly, any for that matter), I think there are some little details that deserve to be discussed or addressed, as a fruitful horological discussion. The biggest qualm I have is the tourbillon. To begin with, the tourbillon is... 

Wow, impressive movement.

The overall look? not for me, but what do I know? I don't own a yacht. Thanks. Vte

what an impressive - and overwelming piece of Horology
