Since my g-7500 adopted slowly but surely, I am already longer looking for a new clock. My attention: G-Shock (I wear for about 17 years) Also easy to read without glasses (reading glasses) Bracelet is supposed to be a bit longer. Did I then ordered here GD 100-1AER and the G-8900-1ER. The GD-100-1AER I liked very good, unfortunately the number of displays are too small for me. Without reading glasses, not really good to see. The G-8900-1ER is a large clock and the numbers are a little larger and wider, not as fine as in the DG-100. Can also be easily read without glasses. The background display is yellow rather dull gold. The clock is limited to the essentials, no Mäusekino no disco ball. The bracelet is long enough so that I can carry the clock quite loose without the band that slips out of the loop. Would say to me, at present the correct clock. Hope it is a good replacement for my 5-year-old G-7500.
