It is a big watch but being WG the weight is a bit more manageable than it would be in platinum. Also the huge deployant balances the weight around the wrist a bit so this helps.
Adjustment of it is not the easiest it must be said. I assumed the button was a quick advance a la my Datograph Perpetual Tourbillon but not so and the moon phase adjustment is a bit more complex too. I guess just a function of getting used to the process.
