The
Patek Philippe ref.
1593 was introduced in
1944.
It was nicknamed the “Hour Glass” because the sides of the case feature a gentle curvature that taper inwardly to the centre from both ends - resembling the lines of an hour glass.
The side of the case is shaped like a curved arc, but some cases feature a discreet peak at the highest point.
Also, some examples feature a crystal which is faceted at the narrowest part of the case, but others feature a curved crystal.
Anyway, last July, I was able to try on a yellow gold example with faceted crystal.
A/ YELLOW GOLD WITH FACETED CRYSTAL
The
lug-to-lug might be a
little too long for my wrist.

But then, I recently saw these photos taken by Discreet Peacock of a yellow gold example with a curved crystal and I think that on a bigger guy than me, it looks wonderful !
B/ YELLOW GOLD WITH CURVED CRYSTAL

Note the
peak, here, at the
centre of the case
arc.

And I also find the
platinum variant with
diamond indexes very
appealing when worn on a
larger wrist than mine !

What do you think?
Do you like the "Hour Glass"?
