Jun 17, 2015 3:02 PM in response to léonieby Winston Churchill,As I said, I was fully aware that the screen only stayed on for 7 seconds if I rotated by wrist to the correct position and about twice as long (but admittedly not absolutely sure exactly how long) if I tapped the screen instead, yes we knew it wasn't possible to keep it on longer or indefinitely, these were the things we discussed when trying to decide if it was suitable as a fob watch before purchasing it.

Jun 17, 2015 3:22 PM in response to léonieby Dan Mitchell1,To keep the watch face on longer, in an average day of 16 hours = 960 minutes, is real costly in battery power. From my single test, above, every 22 minutes of extended ON time costs 10% of battery charge. Now 22 minutes in a 960 minute day is 2.3% extra ON time. So every 2.3% extra face ON time costs you around 10% of battery charge.
Anything significantly longer ON times and you are charging the watch twice/day instead of once !
It is worth it ? "You pays your money ------ "

Jun 17, 2015 5:45 PM in response to julian KAYEby MatthewRN,I use my watch to take pulses all the time. I just rotate my wrist while holding my fingers on the pulse. I haven't had to count a pulse yet, with the same hand I am wearing a watch on. It would be nice to have the face stay on for a longer period of time but I have no complaints about it.

As I have to charge it twice a day anyway, it would not matter much.

Jun 18, 2015 12:54 AM in response to léonieby Winston Churchill,You may have a problem with the watch, I regularly have 40%+ left at the end of the day. I also go out on 3-5 hour cycles where it's monitoring me and working with my phone all the time.

Jun 18, 2015 2:11 AM in response to Winston Churchillby léonie,Thanks, I'll have it checked at the Apple Store. I keep it running on in a workout setting at all times, either outdoor cycle on the way back and forth to work, or indoor walk while I am teaching. It never lasts longer than seven hours at most.

Jun 18, 2015 6:03 AM in response to julian KAYEby davidfromtrappe,OK - After keeping an eye on this thread -
There was ample information about this prior to the release of the watch as has been pointed out to me many times. However, nowhere was it said that this was not modifyable.
Taking a pulse for 15 seconds introduces too much error. Taking a pulse for one minute is too long when a patient's life is at stake. This why the first responder community has settled on 30 seconds. To take a pulse for 30 seconds you need the watch face visible for about a minute so you can turn it on, find the pulse and count for 30 seconds. We don't need the watch face on continuously for tens of minutes. We just need it on for a minute or so up to about 10 times in a day. If this reduces the battery life by an extra 5%-10%, so be it. I regularly have over 50% battery life left after a 16-18 hour day. Rotaing the wrist during the pulse taking is unacceptable as that is annoying and not 100% reliable giving me the chance to miss the end of the 30 second period. That introduces error. When we take pulses, the trend for several pulses over a 15-20 minute period is more important than the actual number. Using a 3rd party timer doesn't work as they don't seem to have implemented the tap on the wrist at the end of the time period. I've tried several and when the display is off the end of the time period is missed. Using built in timer is not possible because it doesn't allow for sub minute times unless you request one from SIRI which is not reliable in a high noise environment.
Even if you are not taking pulses, some people have complained that they don't have time to read a notification before the display goes blank.
Apple has touted this as the most accurate watch and as useful in health situations. Additionally, the watch should work like any other watch. We shouldn't have to purchase a second watch to do this.
Apple needs to give us the ability modify this easily for one-off events. This could be a complication to the watch face that toggles the continuously on display or a double tap on the display that also toggles. This could also be something that is turned on or off ( the feature not the display) in the iPhone Apple Watch app. I have put in a feature request. Others need to do this also.
It is good that this is getting publicity.

Jun 18, 2015 6:13 AM in response to davidfromtrappeby Dan Mitchell1,On the purely medical position - I'd like to hear why you don't use portable battery operated Pulse Oximeters - which in a few seconds after having been clipped on to any finger will give you both pulse and sats., in a continuous readout ?
Horses for courses ?

Jun 18, 2015 6:24 AM in response to Dan Mitchell1by davidfromtrappe,We probably should. However, they cost, they are yet another piece of equipment I must carry in my first aid kit while skiing, they are not as accurate as a well taken manual pulse, and they are not as reliable in a ski patrol environment where the weather could be a blizzard with 30 below windchill factor. Mechanical and electronic devices don't do well outdoors in poor environments. The watch is under my sleeve and warmed by my body. In addition, the fingers could be injured and we then need to fall back on manual pulses.

Jun 18, 2015 6:31 AM in response to davidfromtrappeby Dan Mitchell1,Understandable using a watch in your situation - but is an Apple watch rugged enough for your particular use ?
Do let us know how your watch usage goes.

The operating temperature range for Apple Watch is very limited - you will have to keep it warm in a blizzard https://help.apple.com/watch/#/apd707b42a5e
Operating temperature Apple Watch is designed to work best in ambient temperatures between 32° and 95° F (0° and 35° C) and be stored in temperatures between -4° and 113° F (-20° and 45° C). Apple Watch can be damaged and battery life shortened if stored or operated outside of these temperature ranges. Avoid exposing Apple Watch to dramatic changes in temperature or humidity. If the interior temperature of Apple Watch exceeds normal operating temperatures (for example, in a hot car or in direct sunlight for extended periods of time), you may experience the following as it attempts to regulate its temperature:

Jun 18, 2015 6:41 AM in response to Dan Mitchell1by davidfromtrappe,Yes, but to tell the truth, I do carry a second watch while skiing as getting to my wrist watch under several layers of sleeves is awkward. So I have a carabiner watch on the outside of my jacket. However, when we go into the warm aid room we then take off our jackets and rely on the wrist watch. I won't really know the Apple Watch's ruggedness until next season, but so far it appear to wear well.

Jun 18, 2015 6:42 AM in response to léonieby waynefromtoronto,Huh?
Given the fact that you have to wear the Watch on your skin, keeping it warm in a blizzard won't be an issue.

I don't like to keep metal close to my skin at -30°C. It is very unpleasant, once the sleeves and gloves are removed to be able to look at it. When skiing, I usually keep my watch and the batteries for the camera in a pocket. But that does not suffice to keep them warm enough for more than two hours or so.
