Ever since the first E30 series came along, BMW M3 has enchanted car enthusiasts around the world. The E90 series, that has been with us a few years, is no exception. By many elected the perfect combination of usability and performance. A real sports car, with room for passengers. With its well balanced chassi, its thorough construction and hefty V8, this is almost the perfect core for a race car. But only almost. Ascending liquid temperatures is one of few known issues with these. do88 has analyzed the reasons behind this, and developed a sustainable solution. We have the answer for you!

This is the product for the experienced driver demanding nothing but the best! It´s suitable for track racing, endurance racing, track days or inspired street usage, where there´s no room for compromise in terms of perseverance. This is one of the products in the history of do88 that has taken the most man hours to develop, which is clearly shown in the fitment, finish and performance.

Greater core volume, bigger active cooling area, that frankly is what actually cools the oil, excellent fitment and - of course - vastly enhanced performance, makes us guarantee you will be satisfied!

Best cheap time piece there is
Color: Gold Silver Stainless Steel/Blue Dial-2870
I’ve been a chef for years and having a great watch that keeps time as well as it looks classy is a tough ask when you’re exposing said watch to high heat over the range, extreme lows putting away vendor orders in the walk in fridge or freezer (sometimes up to an hour or 2 at a time), getting popped with hot oil and sauces, and doing dishes when our dishwasher is a no show. I do take this off to make seasoned flour for fried chicken or seafood, but it can easily be kept clean and it keeps time EXTREMELY well. I get several compliments on it from other chefs and even the guests at our restaurants both in downtown Charleston and the resort at Kiawah Island. Just don’t bang the face of the watch into a steel prep table (it will chip or scratch). But it is possible to replace the face at a local jeweler, and at any desired quality or price bracket. I own this watch in several colors and have used them for 2 years now. I’ve been very happy with OLEVS all around.

Affordable, comfortable, and practical watch
Color: Gold Silver Stainless Steel/Green Dial-2870, Color: Gold Silver Stainless Steel/Green Dial-2870
This watch is very good for its price range, of course this isn’t a Seiko, but what do you expect for under $50. I’m extremely excited about this watch and just finished removing some links for it to fit. That’s the worst part removing the links which is very difficult even with the tool that was supplied. Now, we’ll see how long the watch will last and hold up after everyday being worn. It’s a good looking and comfortable watch that’s inexpensive.

Used Watch?
Color: Black/Gray/Digital
The watch is great but the watch had been worn. The protective film was removed and it was loose in the watch box and not on the plastic holder. I bought a new watch not a used one. Joe
