So wanting a white dial around 40mm with 20mm bracelet, saphire crystal, 100m wr, quartz, non auto, non solar, with lume and date narrowed my search to these two Seiko models.
or the SGEH39
Obvious differences the hands and markers and the 45 has crown guards. The bracelets are different as well but it is hard to tell from pictures and there are few videos of these. Lume is very important to me daily so the extra lume on the hands of the 45 are a plus along with the lumed second hand but the red is a negative on that one.
So if any of you own either or both please chime in with some insight both are priced around the $100 mark with the 39 costing slightly less than the 45.
I have one of these arriving tomorrow but am not 100% sure I made the right choice.
