GS adds 2 refined GMT sports watches: SBGM 245 & SBGM 247

GS announced two sports watches today, with dark olive and deep blue dials.




 These follow in the footsteps of the well-known SBGM001, a mechanical automatic movement GMT watch in stainless steel case, on a bracelet. Here's mine in the center, taken in April 2005. 



Let's see if we can indicate the differences with a closer look. The new case has longer lugs and the crown and date window are at 4, not 3 o'clock as would be normal on most mechanical watches. SBGM has a black date wheel with white numerals while the new watches both have a white date wheel and black numerals. The new watches have lume on the hour indicies, and on the hour and minute hands. My older watch has no lume. 



The new watches house the 9S66 movement which beats at 28,800 (it's not a hi-beat) and is able to provide 3 days or 72 hours of running time, vs my old watch containing the 9S56 which has 50 hours of autonomy. Claimed accuracy is the same for all, at a conservative -3, +5 seconds per day. 

The new watches are 40.5 x 14.4 mm versus mine at 39.5 x 13.7 mm. Water resistance of the new watches 20 bar vs mine at 10 bar. All new GS are now covered by a worldwide, digitally-registered 5-year warranty, versus previous models' 3-year warranty. NOTE: This SBGM001 has been running flawlessly since 2005.



So in summary, a more efficient movement, with longer running time, more visible hands in daylight or darkness, in a stronger, more water-resistant case, choice of colors and better warranty. 

Which one appeals to you?

Nice hue.

Is the bezel revolving?

If not, the additional 24 hours marking on the rehaut appears to be senseless. Marcus

I didn’t notice that detail until you’ve said it.

I consider the fixed bezel quite useful

If you are referring to the utility of the tiny lettering (showing odd hours), OK yes perhaps the larger markings on bezel (showing even hours) are somewhat separated from their fellows on the inner ring, but they are also much more visible, for sure. My ...
