I saw the White Speedy in person when bringing my Railmaster in for service at the end of December to the new Boutique. The dial itself is absolutely stunning, it has a depth to it that most white dials don't.
The bracelet was also really nice, I have another Speedy (2020 Tokyo) that I wear on bracelet, and this one felt nicer. Additionally, the Sapphire caseback, which I usually don't LIKE clear casebacks, showed off what is probably the prettiest movement I've ever seen.
Those 3 things together made this an easy order! Sadly, they didn't have any in stock at the Boutique so I had to order, so hopefully I'll get it in the next few weeks.
