Need crystal for Gruen Curvex

#1 Post by JerseyMo » Sat Feb 09, 2019 4:57 pm

anyone know the crystal size for this Curvex, or have one that is available?

I don't have it in hand so can only provide these pic.

First of all: this is a nice watch!
But, it is not a Curvex. Some call these Pre-Curvex which is not true as well. This watch was built around 1937/1938 a obut two years after the introduction of the first Curvex and can be called a "poor mans Curvex". It does notwhere call itself Curvex, not at the dial, not at the movement, not at the Box, which it would have if it were a Curvex. Althoujh the watch back is curved the movement determines whether a Gruen is a Curvex or not and this caliber 500/501 movements are not curved, they are straight.
In fact this watch is the Gruen Master, which was specially designed for Graham MacNamee, famous Master of Ceremonies. It did cost only $29.75 whereas a real Curvex at that time did cost about $50.
So watch out for a crystal for this specific model (not the Curvex Master, this is totally different!)

Took a while but I found the crystal after some searching.
This should be the fitting crystals with size 28.7 x 15.5 mm:
SUC MU175
GS MT377
