Great shot @rompec !
Seems pointless to me. I don't buy the water resistance justification since there are plenty of water resistant chronos like the Omega Planet Ocean chronos that don't screw down the pushers.
I have the same watch and love it. Great for knowing the time around the world while staying put. Not good for travel because you have to set both time and zone at each destination. GMTs are much better suited for that since the home time never needs to be set.
