I bought this watch new in October, 2022. When I got the watch, I started to install a lumed sapphire bezel (from Lumed Ceramic Bezel Inserts) -- other than this, the watch is as new (literally, like new) . It functions perfectly: the bezel-action is firmer than other Seikos I've owned; the crown screws out and back down easily; winding is smooth, the movement is very accurate -- the last week on wrist it ran about about +2 seconds/day; the lume is strong; the case and crystal are in perfect condition; the case is pristine; the original Seiko bracelet is unused, and its stickers have not been removed.
I failed to follow instructions with the first sapphire bezel from LCBI, and they kindly sent me a new one, which I have left in its package. I have the original, Seiko aluminum bezel-insert and the 12 o'clock lume-pip -- I can have that original insert re-installed if you'd like, or have the new sapphire insert installed, or just leave it as is and let do with the inserts what you choose. As you can see from the pics, the bezel is perfectly unmarked -- grip solvent was carefully applied just to the insert so as to avoid marking by any tool.
Here's a link to the LCBI insert with pics:

I bought an Uncle Seiko Z199 bracelet that fits the Willard better (in my view) than the 62MAS-style Seiko for which I originally purchased it. The links are screwed in, and it's been fitted for a 6.5-inch wrist, with room to comfortably go up or down half an inch. I have all the spare links. The OEM Seiko bracelet has never been touched.

I have a pair of FKM Tropic straps, in black and brown, with quick-release spring bars. I'd sell each for $15: https://www.ebay.com/itm/124855649226?
I've been systematically sampling watches (Hamilton, Sinn etc.) that I've always had my eye on, in pursuit of a one-watch watch collection -- or at least a one dive-watch collection. I've owned a Turtle, and an original-size (45mm) Willard homage. While I loved the look of both of those, I found that this smaller version wears a lot more comfortably, especially after a few hours, while keeping the signature shape and comfort of the cushion case.
