How to turn off sounds in the Messages app on the Watch? One of the great features of the Apple Watch is its unobtrusiveness: I can receive a message, look at it, and respond to it without disturbing the people around me with a series of beeps or vibration buzzes.

However, this is only partly true for the native Messages app: When I send a message, either by selecting one of the pre-defined answers like "yes", "great!", etc. or by tapping an emoji, sometimes (not always) the Watch will emit the classic Messages "bwouup" sound of an outgoing message.

I would like to turn off the sound of this app, but so far I haven't been able to find out how. I'm not asking how to turn off the sound of the Watch entirely, but rather for (sending) Messages specifically.

What I've tried so far

I've looked at the Messages settings in the Watch app on my iPhone and the settings of the iPhone app itself, as well as the sounds &amp; haptic and the notifications settings. The latter allows me to influence how incoming messages announce themselves, but I haven't discovered any settings for outgoing ones.

Is it possible to disable the sound of outgoing messages in the Watch's Messages app?

Update

In the meantime, I realized that incoming messages are also accompanied by a sound, if the Messages app happens to be active on the Watch. I would like to disable those sounds as well.
The watch can be made almost entirely silent, but still give you notifications through haptic feedback by going to Sounds &amp; Haptics and turning on both Silent Mode and Haptic Alerts.
