Overview:

Our engineers designed the line of Hi-Tek differential covers to not only look good but address a number of weaknesses of the factory stamped steel covers. First, they started by constructing the covers of thick A356.0-T6 aluminum, which dissipates heat much faster than the factory steel unit keeping the fluid temperature lower under high-stress loads vs. a steel cover. Then for added durability, we added a reinforced center bar for extra strength along with load bolts to help prevent bearing cap deflection under severe loads. The internal shape of the cover retains the smooth round back internally to help keep the fluid flow going over the ring gear to properly lubricate the bearings, the ring and pinion gears. Additional features include a magnetic drain plug for catching ferrous metal particles, MIL-Spec (MIL-A-8625) black anodized finish, machined B&M logo, and all necessary hardware and easy to follow detailed instructions for a quick and simple installation you can do at home. Note: Gasket not Included.

Features:

  • Load Bolts Provide Additional Support to Bearing Caps
  • Magnetic Drain Plug for Easy Servicing
  • A356.0-T6 Aluminum Construction
  • Additional .5-quart Fluid Capacity

Bad quality. Stopped working within a month.
Color: Blue
This watch stopped working the day after Amazon accepts returns. I had only worn it twice. I had another similar watch which worked fine. I don't see any warranties from the manufacturer for this item. So a waste of money. Also for the 30 day return - I received this on January 11, it is February 11 - I should be able to return for refund.

Must wind the time adjustment knob in for it to work!
Its a gorgeous watch and I love the clasp design and band material. It works if you: 1. wind the time adjustment knob with the knob IN/towards the watch 2. pull out the time adjustment knob and wind the side button to change the time or 3. shake it hard- it starts and stays moving easily after that if you are walking/swinging your hand around. I dont know how long each wind/twist lasts but winding it (knob in) will keep it moving even if its just sitting. Options 2 or 3 only keep it moving temporarily. The band and clasp are really smooth and comfortable. The watch itself isnt too thick and the band is extremely easy to adjust to a custom fit (screwdriver and instructions included for adjusting the clasp location). Its really comfortable for an all day wear, is subtle for everyday wear but classy when looked at up close. For under $35 this is a gorgeous, simple watch and significantly cheaper than most of the others I've looked at. Havent tested under water yet though
