It is what it is
Color: Black Aluminum Case with Black Sport Band Size: 46mm case + Medium/Large band Style: GPS Configuration: Without AppleCare+
I mean, I am loving it so far, but tbh I only bought it only because my previous Series 7 one died out of nowhere. That means I can't live without one now, but also be mindful that these won't last forever like a real watch. And no, this one doesn't do anything useful that the Series 7 didn't do. It does last longer on a charge, and that's great. ... show more

Works as expected/advertised
Color: Light Gold Aluminum Case with Sand Sport... Size: 42mm case + Small/Medium band Style: GPS Configuration: Without AppleCare+
Received in good condition. Works as expected/advertised. It is slightly difficult to use and appreciate the many funtions/features offered by this watch. It does take some getting accustomed to. But I do recommend it.

Great watch for value

Best Apple Watch yet!

This has become my favorite watch so far. The heart monitoring capabilities are amazing. As with all of the Apple Watches, the band is a toss away. Fortunately there are a ton of better bands available out here on Amazon.

⌚ I already had a Series 9 45mm but I found over time that it was bigger than I preferred, especially if you put a case on, which adds ~2mm. Since I wanted to upgrade, I got the Dark Bronze with a 42mm case this time. ⌚ There weren't any defects with the construction of the watch. I did an extremely thorough inspection of it directly under a bright lamp. It did arrive a little dirtier than I expected of Apple, the back of the watch (sensor side) had some cloudy residue and smudges on the zirconia, but it cleans with a damp microfiber towel easily. ⌚ I attached pictures showing the case size differences between Series 9 45mm and Series 12 42mm, with guidelines so you can eyeball the difference. It's obviously smaller due to being 42mm instead of 45mm, but also thinner, because Series 12 comes after Series 10, which was when they actually made them thinner. ⌚ I can confidently say the choice to go smaller this time was worth it, from now on I will only choose the smallest case size possible. I wish they would bring back 40mm even. I experience no difficulty with the smaller screen size and love wearing it more, it looks better on my wrist, and feels better due to Series 12 being thinner and lighter than Series 9. There isn't anything I'm left wanting or missing from the Series 9 45mm. 🎨 The "Dark Bronze" finish is beautiful, it's great that they went with a "dark" shade for this, it's very easy to go too bright or cartoony with brown, making it look awful or too conspicuous. This shade is subdued, high class, professional, sophisticated, reminiscent of bronze statues, art, ancient civilizations. If you're someone who usually prefers a darker palette, where your past choices might have been Space Black, Midnight, etc, this would be perfect if you wanted to take a step toward adding more color to your palette, while still leaving one foot in the dark. 👑 The crown on Series 12 was widely discussed as protruding outward ("it looks like Shrek's ear") more than on prior watches. In person it's out there but not nearly as bad as the pictures, I guess due to how cameras take pictures with focal lengths or whatever, I don't really mind it. Having a slightly bigger gap between the crown and case would make it easier to clean, also if you're going to use a bumper case it's actually preferable, since if you had a case on without the protruding crown it would actually be recessed into the case, making it harder to grasp especially if your fingers are big. With a TPU clear bumper case on (the ones without screen protection) it just barely clears the side of the case, doesn't protrude at all. 🔋 The battery life difference between the Series 9 and Series 12 is crazy. I could leave the house with 100%, go out running errands all day, family texting repeatedly (which causes the text sound and haptics to occur rapidly), and come back home with 98%, with the Series 9 I would have come home with 90%. It's not because the battery on my old Series 9 is worn either, the battery health on the Series 9 is at 98% and I had that watch since it was released. I guess that's the difference between the old S9 SiP and the power efficiency of the new S11 SiP. I do maximize battery savings by turning a bunch of stuff off, always-on-display off, analytics off, raise-to-wake off, etc, but those were also off on the Series 9. If you're going to apply a TPU/EPU screen protector (the flexible ones): 🫧 After applying it perfectly you can still have air bubbles. The big ones can be massaged out using the included microfiber towel between your finger and the screen, or the squeegee, push the bubble toward the closest edge with a firm press toward that direction, do this repeatedly, it will make its way to the edge slowly, then out. 🫧 For smaller air bubbles (possibly left by massaging big air bubbles), just leave them alone! Don't think the screen protector failed and don't peel it off! Just wait. If you wait about six hours they disappear on their own. I had about six to eight small bubbles that I was convinced would be there forever, but they magically disappeared after waiting, the screen protector is now 100% void-free. You can still use your new watch while waiting. I also replaced the screen protector on my Series 9 afterward since it was starting to peel on the edges, that one had even more bubbles after application, I had to wait an entire day for those to disappear, possibly because those screen protectors were old, but they did eventually disappear. 👎👎 Also two thumbs way down for the September device rollout, it was a disgrace. The new Series 12 and Ultra 4 watches crashed as much as four times a day, new iPhone 18 Pros crashed on Face ID repeatedly, the issue was so bad, generated such negative press, that they released emergency hotfixes for both WatchOS and iOS. Until they released the patch we weren't sure if it was a hardware defect, it didn't help that their terrible customer service told some people to return the watch to the store. I held off on opening the watch until after the 27.0.1 hotfix was released, since opening it I've not experienced a single crash so the hotfix appears to have worked. Some miscellaneous things that might not be obvious: ❓ You may want to test that all of the LEDs on the back side of the watch light up properly. To do this run a Blood Oxygen test, while it's running check the back, don't move it too much or it will interrupt the test. You should see all of the LEDs lit up solidly, not blinking, four red, four green, in an an alternating arrangement. You can also do this in front of a bathroom mirror to be able to see the back of the watch without moving it. ❓ Use the flashlight mode in the Control Center if you want to test for dead or live pixels. You can swipe between a fully white and a fully red screen, which should be enough to check if you have dead or live pixels on the display. ❓ It comes with a Siri Modular watch face, this is a special variant of the Modular watch face with a special color that matches the case color you picked (ex: "Dark Bronze"), compared to Modular the center complication can't be specified (it uses whatever is pinned to top of smart stack), and it lacks the ability to specify an upper left complication. It looks much better than Modular in my book. ❓ Series 12 and Ultra 4 have two new exclusive complications: "Daily Steps" and "Heart Rate." The older watches don't have "Daily Steps" at all, they did have "Heart Rate", but that variant was just an app switcher (tapping the complication takes you to the Heart Rate app), the new "Heart Rate" complication shows you the real-time numeric heart rate value from the new continuous heart rate feature, so you might want to pick either or both of these complications, since they're exclusive to your new watch. ❓ The new watches track steps more accurately than older watches, on older watches you had to swing your wrist to get it to track steps, this is no longer the case. ❓ You may want to disable the Smart Stack "Widget Suggestions" for many reasons: The suggestions might be wrong, it's annoying when random widgets show up, you want to prevent it from wasting battery both on calculating which widgets to suggest and from the added widgets themselves, etc. To do this, go to the Smart Stack by swiping up from the bottom of the screen, tap the "Edit" button at the bottom, then scroll all the way down to "Widget Suggestions", then disable "Allow Widget Suggestions." This will prevent it from injecting widgets into the Smart Stack. Now you just add the ones you want manually, and move the one you want to show as the center complication in Siri Modular to the top, and pin it. ... show more
