After wearing the W59, I do consider it better than the F-91W. Same functionality, same great legibility, same great reliability, bigger buttons. Works great. If you're not bothered about your watch being some sort of conversation starter, then the only other factor to consider is the price. Dont know about the f91 but this may give you an idea and it is very nicely written. Its about a Casio A158. Practically the same watch only with Steel bracelet and chromed case.

Casio W-86 Review |The True Successor To The Legendary Casio Casio W-86 Review |The True Successor To The Legendary Casio

As you can probably tell from the color and texture, this W-86 is constructed of the same resin as the F-91.and neither Walmart nor Target carry it as far as I know. Personally, I had to buy mine online just to get one. Choices of other Casio models that have the same functionality as the F-91W that have bigger buttons are the W800H, the F105W, and the one I'm talking about that I just bought, the W59. That watch has 4 buttons. If you watch any episode of ELR you will see one button on the right side of the watch during closeups. I think it was mainly the F91, but he did wear the F105 in at least one season. nastavenie dátumu/času sa robí tým istým tlačidlom ako podsvietenie, chcelo by to samostatné tlačidlá na jedno a na druhé. I’ve seen warnings about watches after the battery’s been changed, the integrity not as good. I suspect using the buttons underwater might be risky.

Casio F105W and why I do wear it - menga.net

podsvietenie, kompaktné rozmery, úžasná náhrada za F91-W, jedno z najlepších Casio aké kedy vyrobili. Malé balenie - japonsky efektívne. Vynikajúce kvalitné hodinky zo základnými funkciami ktoré úplne stačia načo vyhadzovať stovky eur za hodinky stačí 20eur a máte postarané ho hodinky čo vydržia dlho. Jedine minus je krátky ramienok ktorý ak máte šťastie tak nasadíte ak nie treba dokúpiť nejaký dlhší. For those not in the know, the F105W is like the F-91W, but with one rather important improvement. The nightlight is a million times better. This is why ILLUMINATOR is so prominent on the watch face. Given [Rotislav’s] results, we’d be far more confident getting our affordable Casio watches a little wet. Obviously, we wouldn’t expect to make a warranty claim if damage occurred from use outside the specs, but it’s clear the watch is far more capable than standards might suggest. If that’s not enough though, you can always set about modifying the watch to improve its water resistance even further. Ages ago, I went for a dive using my a Timex Ironman digital watch, I can’t remember what exactly it was rated for, but I think it was 100m / 300 ft. IIRC after about 30 feet, the pressure is sufficient that the buttons do not work any more- they all get pushed in at the same time because the pressure outside easily overcomes the small amount of atmospheric pressure inside the watch. So I guess it is technically correct that depth and submersion didn’t damage the watch, but it was functionally useless. I suspect that would be the case for this Casio in the article.Although when I lost my F105W I decided to replace it with an A168W (same guts), slightly snazzier and I prefer the metal band. Similar button construction as the F91W here but with the world’s tiniest E-clips retaining them from popping out. The first step was to simply immerse the watch under 5.5″ of cold tap water while pressing the buttons and observing for any signs of water ingress. Already, the watch proved it is far more than just rain resistant, so [Rotislav] decided to disassemble the watch and learn how it achieved this. One model that Walmart carries that does have it is the A168. If you like a small digital with a steel bracelet, that's your watch. But if it's not, the resin version is the F105W...
