Overview:
The original Dominator® took carburetion to another level in 1969 when it was developed for NASCAR® racing. It has been refined over the years and has received its biggest change ever. The Gen 3 Ultra Dominator features a brand new main–body, brand new state–of–the–art calibrations, high volume fuel bowls and sizes up to 1475 CFM!
The patent pending GEN 3 main–body is 5/16" taller than the previous generation! This new height allowed for larger radius air entries which were optimized using Computational Fluid Dynamics (CFD) software to deliver smoother flow into new fully machined, big bore venturii.
The main-body also features an integrated idle bypass valve that allows for idle adjustments while maintaining the correct throttle plate to transfer slot relationship as well as an extended air cleaner flange for easy air scoop attachment when using the available air scoop adapter.
The Gen 3 utilizes high capacity fuel bowls which feature 20% more fuel capacity to eliminate starvation, integrated fuel shelf to minimize fuel aeration and internal baffling to control fuel slosh. Other features include all aluminum construction, 12 hole billet booster inserts, fully tunable billet metering blocks, adjustable external linkage, throttle position sensor mounting points and knurled (hand adjustable) curb idle screws
Each calibration has been dyno and track tested to deliver proven performance!

Everything I expected.
Color: Black/Red
Not the watch I would want as an adult but fits my son perfectly. It’s durable, red and makes him happy. It should last him until he is old enough to get a job and make his own style and life choices.

Timex now poor quality
Color: Blue/Black
These watches used to last me years. The past two of these have died in under 6 months. Worthless junk. Will avoid Timex from now on.
A single drop of water and the button sends the watch into black screen and reset.

Good basic digital watch for women
Color: Black/Gray Stripe, Color: Black/Gray Stripe
Okay, so it's a great watch for women with small to medium wrists. Here's my pros and cons list:
Pros:
- Super easy to set. The package insert does NOT include instructions. This is my first Timex Expedition watch, so I had no experience going in. All you do is press Set and you use the Start and Stop buttons to move up and down, respectively, through the settings. Easy enough!
- I love the simplicity of the watch. It's simple and easy to read.
- It has the day of the week AND the month AND the date. I wanted to make sure any watch I get has these features.
- The watch band seems high quality. It is fabric/nylon, so it should hold up for several years (we'll see I guess).
- The Indiglo is pretty and works great in the dark!
Cons:
- I have to tighten the band as tight as possible in order to prevent the watch from wobbling around my wrist. It may be because my wrist is small and the watch itself is a bit heavy in comparison. I AM new to wearing a watch, so maybe it's just something I have to get used to.
- The display is perfect, but only when looking at it straight on (when facing you directly). If you were to glance over at your watch while you're typing on your computer, you can't see the time. It's too blurry. So the viewing angles are terrible. You can only see the time if you look directly at it. Again, this might be an issue with all digital watches, but I sort of expected more in today's technological world. This is probably my biggest con and biggest disappointment.
- The band holder is also nylon, so I had some trouble getting the extra band into the band holder. Now that I think more about it, I'm not sure what a better alternative would be for a nylon band... maybe if they glued the band holder on to the band, it wouldn't move around so much when trying to insert the band into the holder. Once you're inserted it, it seems to stay in place, though. So that's good. But I can see it loosening up and not working well in the future.
I've only had this watch since yesterday, so I haven't been able to test its waterproofness yet. I will update this review if I am unhappy with the waterproofness.
Overall, it's exactly what I was looking for: a basic digital watch that shows the day and date, with a band that is small enough to fit my female wrist. However, I would have liked it better if the price was $10-15 less than what I paid for it.
UPDATE: I've since moved on to a few other watches since this one. I have concluded that I do NOT like having a cloth/nylon watch band, and I prefer the rubber/plastic bands now. The nylon band takes way too long to dry after a shower, whereas the plastic bands don't need ANY drying time.
There are a lot of good plastic banded watches out there, and I've tried a few no-name brands on Amazon and have been happier with them than I was with this Timex. They are also not as heavy and floppy on my wrist.

Comfortable, stylish, and great for work or casual wear
Size: 36W x 32L, Color: Black
These DKNY slim fit chinos are a great balance between comfort and style. The stretch material makes a big difference — they move well throughout the day and don’t feel restrictive like some other slim fit pants.
The fit is modern and clean without being too tight, which makes them easy to wear for both work and more casual settings. They look polished enough for the office but still comfortable enough for everyday use.
The fabric feels good quality and has held up well so far. They don’t wrinkle too easily and keep their shape after wearing them for a full day. The 5-pocket design is also a nice touch, adding a bit of versatility compared to more traditional dress pants.
If I had to mention one minor thing, it would be that sizing can feel slightly snug depending on preference, so if you’re between sizes you might want to consider sizing up.
Overall, really solid pair of chinos — comfortable, versatile, and good quality for the price.

Excellent value for the quality and fit.
Size: 34W x 29L, Color: Khaki
Love these pants. So much that after wearing the light khaki pair a few time I bout a navy blue pair. I'm 5"5" and finding 29" inseam pants is a challenge, these fit perfectly and my flat butt isn't saggy baggy with the slim fit. They are NOT Skinny in the legs. The material is smooth as silk and I didn't need to iron them after washing. You would pay much more for anything close in a department store. The stretch is great, I can go without a belt confidant they won't fall down.
