There is an IOS app called GATTBrowser that might do it, but I have not tested it.

I have tested GATTBrowser and it can set the time on the watch from iOS, but you have to do part of the work. I don't have an iPhone but I do have an iPod so I downloaded GATTBrowser and tested it. It is impressive, it can read a lot of information from the watch, and can set some of the info, including the date and time. However it does not have an option to take the current date and time from the phone and send it to the watch, or if it does I could not find it. You have to build the date and time string yourself. The string is in hex and consists of nine bytes, 2 bytes for the year and one byte for each of the month, day, hour, minute, second, tenths and hundredths. The year has the bytes reversed. So 2020 in hex is 07E4, you send e407. To send December 8, 2020, 13:50 you create the string 0xe4070c080d32000000 in the "write" field and then hit the Write button.
