Great looking watch at a great price. The green dial is striking under some light, and the gold accents pair well with the overall aesthetic of the watch. The face was a little smaller in person than I expected, but that’s definitely not a bad thing. For reference, my wrist is about 16 cm at the location where the watch would sit. The main downside is the strap it comes with, as it’s very stiff and cheap feeling.

just made it to 8 months of daily wear with my alpinist that i bought in january. I have owned 1 or 2 automatics previous watches previously, but I was a mainly a Solar Quartz type of guy. i just like a level of accuracy that, up until now, automatics didnt really provide. The alpinist has proven to me its absolutely INSANE levels of accuracy and durability. It is bulletproof, period. The accuracy is excellent, period. It is, to me, the ultimate 1 watch to go anywhere and do anything. DESIGN - The time is very legible and quick to read even at a quick glance. for me, only the even number indices being arabic numerals just helps. maybe it is just me. Lume blew me away, I didnt realize that the lume was gonna be that good. Lumibrite aint no Super Luminova. at least none that i have seen. The compass is made fun of, and i can get it. I had thought it was like some form of magnetic compass and that the lower crown was a button, but thats not it at all. Its just a free spinning wheel that rotates the inner bezel. I set it along indices to mark the day of the week so it does have use to me. you can of course use this like any other bezel like on a dive watch, and you can mark whatever or use it to remember whatever you want. Since it is a free spinning bezel with no lock, it can spin out of place, however. just something to consider. As for the strap. Well... i dont like it. i replaced it with a nylon strap. it is 20mm so the world is yours when it comes to straps and bracelets. one thing i did note was that the alpinist does NOT like quick release bars. They like to get stuck and twist and pull on the strap. The alpinist does come with spring bars, but i went ahead and ordered some big boy thick durable ones and all my bar problems went away. DURABILITY - my type of work is not in the office. it involves being pretty physical, and i have not gained the first scratch on my crystal. the sapphire is excellent. I have acquired plenty of scratches on the polished stainless steel, though. i live with it okay, but polished stainless would not let the scratches stand out as well. otherwise, the diashock movement is bulletproof, and i have had ZERO issues with durability THE MOVEMENT - If you do any research online, you will find that some people complain about the 6R35. Their main complaints being the accuracy ratings from Seiko, and Positional Variance. IN MY EXPERIENCE, i have had extremely precise levels of accuracy. I figured out by setting my watch, fully wound, down in different positions, that setting my watch down flat gains about 5 to 6 seconds per day. when i set my watch upright, or vertical, it loses about 5 seconds per day. so what i just do is if i see my watch is running fast, i set it down upright, and if its slow, set it flat. this has let me keep accuracy within 5 seconds for incredible periods of time for an automatic. I accidentally pulled the crown out all the way changing the date to the first for July. I last pulled it out february. it blows my mind. the gshock and f91w that i set to keep track of perfect time, i have had to set multiple times before i had to pull the crown out of the alpinist. Keeping the watch fully wound, worn everyday, and placed in the right positions has given me incredible results. now, if i remove the crown for any reason, i have noticed it wanting to run a bit faster than usual, and i wouldnt call it unpredictable, but it is definitely different. i assume what people do is set the time, see its fast, and just set it because thats what you do with an automatic, then it got set again and now its gonna run silly for like a day or two. if that was all i saw for results, i would call it inaccurate too. I say all of this because i believe it matters a great deal how you are gonna wear this watch. This is my one single, EDC, Go anywhere do anything, watch that i rarely rotate. the power reserve will let you rotate a day or two of other watches, but this watch works best if you never let it die or be reset. it gives you the ability to do that, in what i have seen, but is that right for you? thats up to you. if i rotated many watches and it may be a while before i wear this watch again, maybe i would say its not worth it. all in all, for me, this watch is PERFECT. this watch has been so good its flipped my opinion of automatics as a whole. if this is gonna be your 1 watch that you have forever, this will do you right.
