The original Willard is fantastic and I really like the current reissues.
I think the SRP777 (now SRPE93) offers the ‘best bang for the buck’ as can be bought for under £300 new.
I like the look of the mini turtle (SPB317) and may get one.
Still learning about Seiko references!
Edit: sorry, I was thinking turtles in general rather than specifically Willard’s!
