Comprised of multiple embossed layers of stainless steel with the outer layers utilizing a Viton rubber coating. Compressed operating thickness is 0.040". Cometic MLS (Multi-Layer Steel) Head Gaskets provide maximum sealing performance for todays high output engines and require no sealants. MLS gaskets are ideal for both aluminum heads to aluminum blocks and aluminum heads to cast iron blocks. They can withstand the shearing force created by the two materials. MLS gaskets have increased strength because they are comprised of multiple layers of stainless steel; which also creates the ability to rebound and resist corrosion. The outer layers are embossed and coated on both sides with Viton (a flour elastomer rubber based material that is heat resistant to 250 C/ 482 F). Viton is designed to meet the demands of a variety of harsh sealing environments, load conditions, and surface finishes. The center or shim layer is uncoated stainless steel, which can be varied to accommodate multiple thickness requirements.This Part Fits:

Typical Ironman quality
Color: Black/Silver-Tone
This is my fourth Timex Ironman watch. I own many watches, and prefer the Ironman for casual wear and sporting activities as well as swimming and snorkeling. I decided to replace an earlier model with this one rather than pay to change the battery.
The Ironman has changed very little over the years since its introduction in the '80s, with the exception of cosmetic improvememnts and a larger display. I selected the "oversize" model as I was looking for a little more heft to this model. This watch fits the bill, not as chunky as my G-Shock. A pleasant surprise was the weight of the watch. This model is lightweight, another advantage over the G. It's larger than the typical Ironman model, but about the same weight. The band lacks the stiffness of some other Timex and Casio models, and is quite comfortable.
Typical Ironman functions are unchanged, and the ability to "hide" various functions makes operation of the watch more efficient. There are three time zones, useful when traveling, as well as the usual chronograph/timer and alarm functions.
I haven't worn the watch in the pool or ocean yet, but if experience is any guide, I expect no problems. I've never had an Ironman leak, whether during water sports or snorkeling.
These are great watches for the money. I prefer 200 meter water resistance for this type of watch, but Timex has yet to build an Ironman 200m that doesn't overwhelm my wrist in weight and size. I'm not a big guy, and they are simply too large for my wrist.
Looking forward to years of service with this watch. Definitely a good timepiece for the price.

Will not be disappointed
Color: Black/Blue
Keeping in mind that I received this item yesterday (2/24/16), I absolutely love this watch. The reason I have so much confidence with this watch is because I've owned one other Timex similar to this one, and it served me extremely well and is still able to do so. First off, this watch is certainly aesthetically pleasing. The blue color around the face of the watch and outline in the band, goes really well with the black frame. It's just an overall nice looking watch. More importantly, the quality seems great. As I mentioned, I've owned a Timex expedition, which I've had for more than 2 years, and it's still working perfectly fine. The watch seems like it's put together very well and there's no loose or flimsy parts. One complaint that many people seem to have with Timex is the quality of their band. Unfortunately I'd have to agree, since the band on my other Timex that's still working like the first day I got it, cracked and broke and is only being held together by the nylon fabric on the other side of the band. You're not going to have that problem with this watch. It's a full nylon band with Velcro adjustment, for precise fitting. it feels extremely comfortable and you won't need to worry about the band cracking (although I'm sure there will be certain defects in a mass produced bunch). I will use this watch for work and running, and rarely plan on taking it off. Just to give you an idea, I also have a garmin gps watch that I love and obviously has more functions than this watch. However, the second I received this watch, I slapped it on and put my garmin to the side. This watch also looks amazing when you wear it. I'll update this feedback as needed, but I'm confident this watch will serve me for years to come, just as my other one has.

Greatest watch I've ever had, but changing batteries is near impossible
Color: Black/Blue
This is the 3rd time I've bought this watch. Same brand, same or very similar model. It has a chronometer, timer, alarm, and of course the clock. It has something I think is for "occasions" but I don't know what it does and don't really care about it. The watch is durable. It uses battery power efficiently. The indiglo is second to none. I just really really like this watch.
Having said all that, if you want to change the batteries, good luck, you'll need it. Once you manage to get the backing off of it and open it up (which is a little tricky in itself), it's like a comedy routine where you see some stooge open an electrical device and a buncha parts and springs go flying everywhere. And of course, they are so tiny, you'll never find them once they fly out. That was the exact scenario I found myself in the last time I tried to change the battery. It made me so mad I actually bought another brand of watch that I thoroughly researched. But that watch DIDN'T use battery power efficiently, and it had a host of other minor problems that added up to the conclusion that it was not nearly as great as this Timex. So, for the 3rd time, I found myself buying this Timex watch.
So it's a wonderful watch in every way except longevity because changing the batteries has historically been a nightmare for me.

A better Ironman design
Color: Black/Blue
I've been a fan of Timex watches for most of my life, paying about $30 for one in the 1960s, and that hasn't changed at all in 2010 because I'm still paying about $30 for my Timex watches. It is a rare case indeed when the quality of a product continually improves over several decades while the price remains the same. And as John Cameron Swayze would say in those live ads during the early years of TV, "Timex takes a lickin and keeps on tickin".
The MEGA deserves a good review after I have been using it for a while. You might also see it advertized as the "Oversize" because most distinctive about this design is its size, so tagging it with the name MEGA is entirely justified. It is massive in comparison to most of the other Ironman series of watches, and what seemed at first to be just another unnecessary Ironman 30 Lap design has turned out to be one of my favorites for all-around wearing. This new design keeps the clockworks of the standard size 30 Lap Ironman watches, it counts up and down, programs the same, has several alarms, and of course, it has the Indigo night light that works so well.
This is one of five different versions of the Mega available in the USA, and the only one with a Fastwrap Velcro wristband with blue striping and a matching blue bezel. Velcro wristbands are a favorite among many athletes and when it wears out, it can be replaced with either an identical factory band or one that is made of urethane rubber.
Overall, the Mega is a good choice for runners in need of a new 30 lap Ironman who can appreciate having a watch that is distinctively larger and what I would consider to be much better in appearances over the others of standard or mid size Ironman dimensions.
