Surprising good!
Color: Brown/Blue/Stainless Steel
I purchased this watch on whim, I was pleasantly surprised at how good it looks. I just love the design of the face. THe quality is good. I did change the strap for a premium leather. It comfortable to wear. Worth the money in my opinion.

Really nice and unique watch
Color: Black/Black/Black
This watch really caught my eye on Amazon. Every once in awhile you order an item and it looks better in person than it does in a picture. This is one of those items. It looks really great in person! I collect mostly unique watches that look different than a normal watch. What is really unique about this watch is that it has 2 separate second hands. One that is always ticking for the time and another one that starts going with the Chronograph. Not sure I've ever seen that on another watch. Sure I've seen subdials that do this, but this is 2 full size second hands. And they look different also so they don't get confused. I've never seen this one in a store which is a shame because I think Timex has some great watches right now and I don't think a lot of people know about them.

nice but.
So, this really is a nice watch and if you can get it on sale it's a bargain. The bracelet is junk, with hollow end links. I would recommend replacing that with some type of fabric or rubber type strap. The reason I took one star off is because the chrono function isn't the best style. If you don't plan to use it much or only plan to use it for 10 minutes or less that's fine. More than that and the minutes counter flies back to zero and starts counting again which can be confusing and the next register is the combo 24hr and chrono minutes/hours counter which isn't easy to use for timing say 30 minutes or so. The standard type chrono counters are way better by design and Timex sells another one with standard counters with neat multicolored registers for less money. Otherwise it's a solid watch comfortable to wear not too big or thick or heavy. Of course it has mineral glass for the xtl so you need to be careful or it will scratch pretty easily but for the price.....

Value-packed chrono offers so much
I love this watch. Dial and movement are fascinating. It’s quite a show when the chrono is engaged, the timekeeping central seconds hand conyinues sweeping around, and the chrono’s central seconds hand is also sweeping. So you have two central seconds hands chasing each other around the dial when the chrono is engaged. On the retrograde subdial displays, time for a second time zone is displayed when chrono is not engaged. Elegant logo counterweight on one hand. Lots of content, complication and engagement for very little money. Highest recommendation for those interested in a watch that has a lot to offer.
