Looks like it came out y'day!
Here’s to the next 25 years. 🍻
In 25 years, I’ll be 89. May not last that long, but the watch will still be showing the correct time, month, day of the month, year and corresponding moon phase! May be too large for my daughters’ tastes, but a son-in-law will certainly appreciate it!
I had the titanium version at one time but decided I didn’t need two GST perpetuals. To this day I still regret selling it.
Sadly, none of my three PC's had worked properly in the years I had them. But, my GST titanium was my favorite... 👍
I have the titanium version and I love it too. It’s not as versatile as the steel versions, but the more sporty look is fine for my use case. My watch also managed the jump to 1 March overnight and all seems well with it. A relief! All the best, Jon
