Having both a sumo and a gs spring drive I can tell you there is a very big difference between them and the sumo is a great watch which means the gs is super great or something like that.

The only real weakness of the sumo is the bracelet seems a tad narrow and is not as high quality by a country mile as the bracelet on the gs. The fit and finish while excellent on the sumo doesn't approach the GS but it can hold it own in most diver circles quite nicely thanks. The most obvious difference though is the movement. it is a fine movement but not the spring drive and its not quite as accurate. However after having said all that I love the comfortable feel of wearing the sumo is about as good as the GS.
If I were a serious diver but choose not to go the dive computer route the sumo give a huge bang for the buck at about six hundred. compared to the rolex the rolex diver looks and feels better and is more accurate and with great fit and finish but it also costs almost fifteen to twenty times as much.
Sumo is a terrific bargin in dive watches,
