Una buena comparativa aunque algo antigua sobre dos relojes que me gustan, aunque me quedo con el GS por algo más de 200$

GS SBGR023 Dimensions (mm):
Case excl. crown: 37
Visible Dial: 28.5
looks considerably smaller then the AT
Crystal: Sapphire with inner and outer anti-reflective (AR) coating, very effective
Lug to Lug: 44
Height: 12
Lug width: 18
Bracelet tapered from 19 to 17 at clasp
WR: 100 meters, non-screwed crown
Weight: 125 grams (bracelet adjusted to 6.5 inch) creating the impression this smaller sized watch to be very heavy!

Omega Aqua Terra Dimensions (mm):
Case excl. crown: 39
Visible Dial: 31.5
3mm larger makes the AT dial look a lot bigger
Crystal: Sapphire with anti-reflective (AR) coating on the inside of the crystal according to Omega
Lug to Lug: 46.3
Height: 11
Lug width: 20
Bracelet tapered from 20 to 17 at clasp
WR: 150 meters, screwed-crown
Weight: 120 grams (bracelet adjusted to 6.5 inch) due to a relatively light bracelet
