And, we offer the lowest possible price, a one-year warranty and free shipping. If you'd like to see more photographs or more information about this specific watch, the link to this watch will be located below in the description. So, I'm gonna go ahead and show you what you'll receive when you buy this watch brand new, in the box. I will go over the case, the back of the case, the bracelet, and additionally, I'll show this watch on the wrist. So, when you buy this watch brand new, of course, you get the watch, you get this lovely Rolex box, and located at the top of the box will be a pocket that you can pull down that has a booklet of information for the watch and additionally, the warranty card here. So, let's move on to the watch itself. As you can see here, very, very beautiful watch. The dial has a nice black color and black is a very versatile color when it comes to casual dressing so this very nice so far. It's already having a nice, gorgeous bezel all around with those diamond studs along with the hour markers being diamond, as well. As you see there. Let me show this under light a bit. Very, very beautiful. The size of the watch is on the smaller side, it is a 31 millimeter in diameter watch. It has a cyclops lens over the date, on the three o'clock position here, for easier viewing. And the crown is also located at the three o'clock position. This watch keeps a water resistance up to 100 meters or 330 feet, as long as the crown is nice and snug and tight against the case itself. As you can see, the watch is all stainless steel, there is no gold on this watch. But, it's still a very, very elegant watch. So, let me show you how to adjust the time and set the date and such. With most Rolex watches, all you need to do is go counter-clockwise to pop out this crown into the first position which let's you wind the watch. Just 20 times clockwise and any more is a little bit too much cause you might damage the watch. You actually begin to feel a little bit of resistance once you try to wind the watch past 20 winds. So, you pull out one more time, that brings you to second position which let's you adjust the date. As I said before, this is a quick set and date feature, which is very nice as you can see. Very simple, very easy for me to adjust the day I want. I want it to be the 7th, easy. Older models, you'd have to go all the way around to set the date, a little pain, but honestly, as cool as that feature is, I feel like I wouldn't even want to put this watch down so it probably wouldn't need that much adjustment anyways. So, pulling out the crown one more time, as I just did, will let you adjust the time. It'll stop the hack movement, which is the second hand moving here, as you can see it's already stopped. And you can just adjust it to wherever you need bidirectionally. And always, push the crown in, the hack movement will start again. And all the way against, and always make sure to tighten that crown against the case. You don't want water to get in your watch, so always make sure, just double check, it's nice and snug, good to go. Alright, so let's move on to the back of the case. The back of the case always kept true to the Rolex quality. Very nice, very simple, has that just very basic fluted design all around and it's just a simple oyster case. The movement of this watch, is a self-winding automatic mechanical movement, meaning that, if you were to walk around with this watch on your wrist, it would wind itself, as there is something called a osculating weight that moves around and always points downward towards gravity so, as you move around that weight's always jiggling around and that'll keep that watch continuously wound. And that will keep it going. So, let's move on to the bracelet. As you can see, the bracelet is an oyster bracelet, very nice, very beautiful. I particularly like the oyster bracelet because it has that nice mirror polish in the center, as you can see there. And it has a nice reflectiveness, gives a good shine. It also has that brushed steel on the outer parts of the link. It is a three piece link, it has one, two, and three. Very cool. And, the clasp is located right here. It's just a very simple safety oyster clasp. As you can see there, it just pops out very nicely. But, it is a very strong clasp. It fits very snugly, very nicely, so you won't have to worry about this watch ever trying to pop out and falling off your wrist. So, the Rolex name is engraved on the clasp itself, right there. Very beautiful engraving. Go ahead and close that. An just show this all around real quick. Very nice. Let me go ahead and show you this on the wrist now. Once again, right there. Has a good old snapping. Alright, so here is the watch on the wrist. Once again, look at that dial, very beautiful. If you can imagine this in the sunlight, oh my gosh, the sun hitting those diamonds make a very vibrant colors and it's just very beautiful all around. Let me go ahead and show you the bracelet all around too. That's beautiful. Alright, so if you have any other questions about this watch, please leave a comment below.
