The Ultra does measure heart rate while swimming. If HR is not showing up on the locked screen while swimming try the following:
Go to Workout on your Apple Watch Ultra
Find “Pool Swim” and click on the 3 dots on the upper right
Now click on the pencil icon on the upper right
Click on “Workout Views”. Now you can customize view metrics and turn on/off different screens

It should be able to measure your heart rate during a swim workout. For more info, see the 'View splits and sets' and 'Get better results' sections in:

Many thanks for your response. I agree the Apple Watch theoretically should measure HR in the water but your ref says it might not. My current Apple Watch does not however, with new sensors in the Ultra, I'm wondering if that model does measure HR.
I can find no ref in Apple literature that it can do this.
The only wearable sensors I know of that measure HR in the water are the Whoop band and the Oura ring. Would be great is the Ultra could do it and until I know for sure, I'm not going to spend $800 for one.
Thanks again
