| Notes | Peterson 572 is a reliable electronic LED flasher in the classic round 2-prong format. It provides a consistent flash rate even with low-draw LED lights (unlike older thermal flashers that often hyper-flash with LEDs). Simple plug-and-play installation makes it a popular choice for fleet upgrades and aftermarket LED conversions. | ||

No instructions
Color: Black/Negative
Watch is good, but it came with no instructions bc this is very confusing to figure out. Backlight is great effect and really nice for the value. Easy to see and read

Functional and great look!
Color: Black, Color: Black
This is my third watch I’ve had in the last 10 years. I bought my first one in 2014 when I was doing triathlons. My second one just died after surfing/working in a hospital with it for the last 3-4 years. I could of just changed the battery but for $40 and it will last, I thought hmmm let’s just get a new one.
No complaints! Shipping arrived in 2 days, and the price can’t be beat. If you are looking for a simple watch to wear and not having to worry about getting it messed up this is it! I had a garmin 410xt that I had to charge etc but this watch is extremely convenient and comfortable. High recommend!

Not great...

The dial is so dark that I can barely see the numbers. Very, very disappointing.

PERFECT
Color: Black
Watch is light weight. Has a good feel on the wrist and easy to read during the day and easy to read with the indigo back light at night. I have large wrists and this size is good. For smaller people it might be to large. The functions work well and its water tight. Its durable and keeps on ticking.
