Now, since there will be two types of sensors that detect yuour heart (IR, and electrical) will the Series 4 work better on tattoos?
I've had previous generations but they wouldn't work properly on my wrist due to tattoos.
They would lock frequantly due to not detecting being on a wrist (with dark tattoos).

Any info on this?

Doubt it, the main sensor is still optical as far as I understand. Electrical is only triggered by ECG?

I'm really hoping for this too. I use the Epoxy Bottle Cap Sticker workaround, which seems to work fine keeping the watch from locking when on my wrist. However, there is some weird power degradation that can take place (I've gone from 100% charged to 10% charged in an hour), and sometimes getting the watch to charge overall can be tricky. Since there is a single optical sensor, I'm hoping its stronger and can see past the tattoo (which is the reason the epoxy stickers work - it magnifies the skin to see past the ink). I'll have to check it out when they have them at the Apple Store, but hoping someone can beat me to it with some good news.

People will start receiving their watches today.
I'm really curious about the answer to the question if the new apple watch works better on tattoos.
Please let us know.

I have a tattoo on my left wrist and my series 3 occasionally loses connection. I’m not sure if it’s because of the tattoo or because I don’t wear my watch tight enough. I like it slightly loose instead of being snug which might play a part. Either way..it doesn’t lose connection enough to the point where I’m frustrated...just annoying at times.

A fix..which isn’t ideal if you use Apple Pay or heart monitoring, is to turn off wrist detection. Like I said it’s not ideal but you’ll never lose connection and if you lay your watch down anyone can see what’s on it.

Praise all the Apple Watch engineers!!!!!

My left sleeve is fully tattooed til my fingers. Apple Watch Series 2 lost connection and was not able to detect my heartbeat properly!

Apple Watch Series 4 stays connected and measures properly!

Verified it with Apple Heart Beat Meassure App and HeartWatch, compared to my Polar H7 chest strap! Discrepancy of 2-3 bpm, obviously due to different intervals of measurement!

Sooo in love with my Watch right now!!

I have full sleeve tattoos, my Apple Watch 3 locked itself often through out the day and was very annoying, even more annoying was when the fitness app kept pausing mid workout. I’ve been wearing my Apple Watch 4 since lunchtime, it has not locked itself yet which is a good sign, I won’t be using the fitness app until the morning but I’m pretty hopeful that all will be ok with this new design of sensor.

That’s great to know! I wonder why Apple has never addressed this?

Because then they would have to admit, that the old watch had problems with it ;)

Not really, they officially always said on their support documents that it is not fully supported.

It is like iPhone 6S vs. 7. 6s no dust or splash resistant. iPhone 7 IP67 verified.

This is sounding hopeful guys! I'll not get my watch until the first week of October, but looking forward to it more now. I hoped it can handle my black / red / grey sleeves!

tested it a bit further.

If I place it directly on top of almost solid black ink, then it looses the connection. But on black shading with red lines and some free spots it just works.

So I guess, as long as you do not have a full black sleeve it "should be fine".

I have been using the series 3 and now the series 4. I never had locking issues, but the heartrate wasn't always 100%. I have a black portion of my tribal tat going straight down the middle of the arm to the wrist, so it's in the worst possible pace for these watches. But with the Series 4, no issues so far. Reads my heart rate without issue, every time. See below.

Cool band with the blue parts. Is this an official nike band? Never seen it before in that color

I hope both pictures gives you a good comparison what works and what not.

Another awesome arm of ink!
On the attached my S3 will read the heart-rate (but it fluctuates) in the green area, I'm hoping to get a reading in the 'right' wearing position, more towards the red position.

OK, figured out why some of you are having issues with the watch locking on previous watches you had and why it isn't now. Has to do with settings

I found it on ebay I believe. It matched the color on my Nike ID custom shoes, so I got it. No idea if it is Nike or a knockoff. Feels like the real thing, but it is probably a knock-off.

Guys I’m happy to report I’ve been wearing my Series 4 all day on my sleeve and have not had 1 disconnect. Very happy!
On the Series 3 I would’ve had 1 or 2 disconnects by now. Looks like they improved the sensors on the 4. I am in love with my 44mm SBSS. :)

So which setting are you thinking of?
