GW-M5600 too small? No worries...

Here is the perfect solution...

:-d

 

I do not actually have the GW-M5600BC, but I do have the GW5000. I think their sizes are either equal, or, they are so close as to need a micrometer to tell the difference. I know that all three of my 5000 series watches are the same size, to the naked eye: DW5600C-9v, GW5000-1JF, G5600-1JF

 

the spec are as follows,
GW-M5600: 46.7 x 43.2 x 12.7 mm, 51.7g
GW-5000 : 48.9 x 42.8 x 13.5 mm, 73.8g

i believe the GW-M5600 should be the same size as GW-M5600BC (BC version is 101.3g), and the new GW-S5600 is also the same size as GW-M5600.
i have swapped the GW-M5600's strap and bezel with the GW-S5600,

below is a pic for the modified "GW-S5600" and GW-5000,

+1 - I was going to say the 5000 would be slightly thicker on the wrist due to the screwback and slightly thicker steel case.

 

I know as I've got a DW-5600B bezel on one.... ;-)

 

Here's a direct comparison between a modded GW-M5600 and a GW-5000. The 5000 is bigger.
