And it won't be my last.
Wanted a bronze watch and after watching YouTube reviews, took the plunge.
The watch arrived quickly, and it's quality amazed me.
Start with that beautiful blue sunburst dial. The only watch my wife loves.
Strap, wow. Why can't other makers do this nice?
Hacking and hand winding? Check.
And now that lume. Never imagined lume so bright and long lasting. All night!
Case is acquiring a nice patina, too.
Just ordered me second San Martin.
I was looking for another 39/40mm for my collection and the Mark 18 bronze checked all the boxes. My only wish is that the date version came with a logo. The dial looks a little sparse. I'm also very disappointed in the rewards program. I've bought 4 watches and spent almost $800 and I have 140 points. It's not even worth keeping track. You should just eliminate it.
Nice and neat watches, good quality tools and leather strap. Lum lasts for the whole night. Power reserve more than 1,5 days. Customer’s service is perfect
Solid seller and the bronze is fantastic. Strap is amazing on its own. Very well made. Lume is a torch. Case lug ends are fairly sharp to touch. Buckle is sharp enough on edges to dig into my wrist, even loosely fit. Strap and lume are fantastic. Feel like I got my $$ worth but will have to replace the buckle. OUCH!
