I picked this one up as an impulse, and have been enjoying it, but I need to slim down the collection a bit. It's a 1/500 LE Seiko Fieldmaster made in collaboration with Japanese streetwear brand Beams. It has all of the functions and dimensions of a standard Lowercase Digi Tuna, but in bright orange with a negative display. If Seiko made a G-Shock, this would be it. But this looks cooler and has 22mm lugs, so it can accept standard straps. The diameter is big, but the lug to lug distance is tight (as Tunas do), and it's not as thick as it looks. It's also very light weight and comfortable. One fun function is a mode that shows you solar charge information. The left side of the display shows the current charge level. The main display, as well as the graph on the right, shows the current strength of the light you're in from 1 to 11. It also has a backlight that lights up for 1 to 3 seconds when you tap once on the crystal! **Name:** Seiko Prospex Fieldmaster Lowercase Beams Limited Edition **Reference Number:** SBEP021 **Diameter:** 49.5mm **Height:** 49.9mm **Thickness:** 14.3mm **Lug Width:** 22mm **Weight:** 80g **Movement:** Seiko Caliber S802 **Water Resistance:** 200m **Power Reserve:** 5 months (20 months on power save mode) **Crystal:** Hardlez **Crown:** Push-button **Bezel:** Bidirectional, friction **Strap:** Silicone Excellent condition, no scratches or dings.
