At the end of a countdown, alerts are issued by either a vibration or a tone plus LED flash operation. The large face of the GD350 is configured to ensure that the countdown timer is easily seen in the dark. And there's another IMO major flaw on the Timex - the watch cannot be completely muted - the watch still beeps when you start and stop/reset the timer and stopwatch - the hourly signal can also not be muted and it can only be accessed from the main time-keeping menu - not from the alarm menu like on the Casios. And the Timex has the famous inverted illumination which I really like (some Casios have it, too but it should really be incorporated more often as it makes for a very nice and nightvision-friendly illumination): The pic is not too good - looks like the camera focussed on all the dust that I didn't even see before I looked at the pics on a computer screen :-d - but I think it shows the ghosting effect well enough.

Once the timer is running the upper part of the display indicates the start time and the lower part is for the running timer: stopwatch - 24 hrs - no current time displayed but if you want a stopwatch with current time you can use the timer and set it to 1 min - so you basically have a 99hr stopwatch with 1-min prestart countdown time-keeping, 24hr mode, weekday, date (date format can be changed between DD/MM and MM/DD), two seperate timezones can be accessed from main screen

Definitely worst of all but that might also be because the display is not as recessed as on the W-735H and GL-7500. When I hold the W-735H next to it and tilt them both the display seems to start ghosting at about the same angle. The button tones on the mode button can be switched off for discreet operation. Pre-set alarm or timer functions remain active.

Flash alert - Flasher with buzzer that sounds for alarms, hourly time signal, countdown timer time-up alarmThe settings menu is a little more user-friendly on the Timex however - some pics I took of the timer setting - you 1st press the adjust button (at first I thought it needs to be held but that's not the case - you only need to press it once) - then the watch displays "timer set" - then "set" and on the right side the watch has a blinking "+" and "-" next to the buttons - on the left side "done" and "next". Pretty easy and intuitive but really not that much better than on the Casios once you're used to them. Upwards and downwards scrolling is done with the upper and lower button - on the Casios it's reversed.

Indiglo reversed illumination with night-function (once activated every button press will illuminate the display and the illumination will stay on as long as buttons are pressed, which is also true when nightmode is not enabled) The GL-7500 and W-735H have the advantage of a one-button access of the vibration feature which on the Timex and GD-350 can only be activated from the settings menu. On the Timex the illumination also flashes with the vibration and on the GD-350 it flashes with the alarm beep and timer beep - both cannot be disabled. So you cannot set the GD-350 to just alarm beeps without LED flasher. But that doesn't bother me much since I always have it on vibrate anyway. I really like that design - the display layout and form factor reminds me a little bit of the vintage Mudman DW-8400. The acrylic crystal is recessed and well protected - the buttons are a joy to use. Display contrast is also very good. The pie-chart indicator for VIB, SPL, ALM and SIG is also much more useful than the tiny ones on the GL-7500. The gray model is the nicest to my taste but the others look pretty nice, too.

The W-735H and GD-350 both feature the "super illuminator" which is a little too bright - the W-735H looks even slightly brighter than the GD-350 (the pics are a little overexposed - so they are both not really as bright as on the pics but still can be used as an emergency flashlight): Auto Light: The watch face will illuminate automatically when you tilt your wrist towards you.
