I've wanted this one for a while!
There are already a couple of quite complete reviews, but here is my impression after almost 2 weeks:
What made me want this one:
- (relatively) simple dial. I'd like it even more without "Eco-Drive", "Radio-controlled", WR20 bar or titanium and the promaster logo (which also looks like a military pheon / broadarrow)
- Lumed numbers. Presence of 5 minute numbers & minute markers
- Hardened titanium ("duratect")
- Sapphire crystal
- Day & date. They change in a quick way on midnight.
- Perpetual calendar
- Eco-drive light powered quartz
- "Perfex" technology: hands hit the markers perfectly. (Great, because on my Citizen BN0100 "Excalibur" the second hand is far off).
- Radio time sync (albeit only Japanese JJY frequencies)
- Quick timezone changes (only full hour jumps), provided you have a toothpick or similar to push the little button with.
Overall a great watch!
Without radio sync it has normal quartz accuracy of ca +0.3 seconds per day.
I've been able to sync it with my computer with this site: Fukushima: online JJY time signal emulator Fukushima: online JJY time signal emulator.
Perhaps in future I'll build a Raspberry Pi sync stand, like this one: https://hackaday.com/2018/09/10/no-s...n-transmitter/
The lume is easily readable during the night and morning.
Flaws & nitpickings:
There are no half links on the bracelet, nor different holes on the clasp. It's either too tight or too lose for me.
There is a 3-step extension thing on the clasp. It gives roughly the difference between one link. The ideal for me would be to remove one link and have it in the middle step, but that kinds of defeats the purpose of having that thing for quick adjustments. I'd rather have a half link or at least a normal clasp with multiple adjustment holes.
The day and date wheel do not have the exact same color background.
They don't align horizontally perfectly. The date shows up a hair above the day. I also have the impression that the disks are not on the same plane, that one is slightly more elevated than the other, but I'm not entirely certain.
The font used on the date wheel has a different look and kerning than the one on the day wheel (come on watch manufacturers, is this really so difficult?)
The lume is applied in a thick way, but there is a very minor 'orange peel' effect on the big marker. It's very slight, you only notice it from close-by with strong lighting and from certain angles.
Overall the only thing that bothers me is the difficulty in adjusting the bracelet, the other flaws don't detract from the enjoyment.
Date slightly higher than day (I put red lines to help indicate, but it's quite obvious on the wrist).
Different color background, different font & kerning & still slightly higher
Slight 'orange peel' effect.
Lume (didn't charge it up, this is after an entire night in a dark room)
