Timex Datalink is flight certified by NASA for space missions and is one of four watches qualified by NASA for space travel. The various Datalink models are used both by cosmonauts and astronauts. For instance during Expedition 1 the crew log for January mentions:
We have been working with the Timex software. Many thanks to the folks who got this up to us. It seems we each have a different version of the datalink watch, and of course, the software is different with each. Yuri and Sergei are able to load up a day's worth of alarms, but Shep has the Datalink 150, and this has a 5 alarm limit. So 2/3 of the crew are now happy. All this is a pretty good argument for training like you are going to fly-we should have caught this one ourselves in our training work on the ground.
In another part of the January log it is mentioned:
Missed a whole comm. pass over White Sands . We need to get the timex watches working so we don't overlook these calls.
while in another segment of the same log:
As 5A is now delayed, we would like to request the "timex" watch software if it is available on the ground-a file that can be uplinked to us. This will help us manage our day as we can load comm. passes into the watches.
and from the February and March crew log of Expedition 1:
We copy the request from Houston on the timex watches. We will keep using the ones we have onboard-there are some workarounds we can apply that will help the limited "alarm" situation. We don't request any more watches be sent up on 5A, but thanks to all the crew equipment folks for asking. As a heads-up to Exp 2, any plans to use the timex download capability should include more laptop IR transmitters. We have 1 onboard, but more will be required if the next crew wants to fully use this capability.
The laptop IR transmitter mentioned in the February and March crew log is the Timex notebook adapter. "Exp 2" refers to Expedition 2 and the log mentions they may need more notebook adapters for the upcoming expedition.

Famous quotes containing the word space:
“Stars scribble on our eyes the frosty sagas,
The gleaming cantos of unvanquished space . . .”
—Hart Crane (1899–1932)
“If we remembered everything, we should on most occasions be as ill off as if we remembered nothing. It would take us as long to recall a space of time as it took the original time to elapse, and we should never get ahead with our thinking. All recollected times undergo, accordingly, what M. Ribot calls foreshortening; and this foreshortening is due to the omission of an enormous number of facts which filled them.”
—William James (1842–1910)
