Mahle Original Premium Piston Ring Sets
Mahle Original piston ring sets are designed to be installer-friendly. They are pre-lapped to seat immediately, virtually eliminating break-in time. Ring materials and coatings, as well as ring tension, are all optimized for reduced friction and extended life in each application. The compression rings feature a barrel-faced contact area for more efficient compression and CNC-controlled gap chamfer to optimize compression and reduce blow-by. Intermediate rings have a reverse twist design for better groove side sealing, and taper race machining to enhance contact. The CP-20 oil ring assemblies feature a 20 degree ear angle, an exclusive feature that provides the best possible side seal against the cylinder wall, and a special chemical polish on the oil ring expander offers enhanced oil drain back. Mahle Original piston ring sets provide unmatched quality and ease of installation, making them the rings of choice for today's engine builders.

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...
Color: Black/Negative
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.
