The accuracy of caliber NH35/4R35 is between +45 / -35 seconds per day. This rating is based on normal daily wear on the wrist in temperatures between 5 ºC and 35 ºC. When testing your watch for timekeeping, make sure it is fully wound.
This San Martin MM300 is a good if not great watch. Case and bracelet finishing are very good for the price, with clear and sharp polishing and brushing. Bracelet feels solid, and link resizing (pins and collars) was decently straightforward. Dial/hand/bezel lume is easy to charge with even just regular indoor lighting, and shines like a torch given stronger light exposure. Bezel action is solid and ratchety, with a good amount of resistance (not too hard, not too easy). Movement is running like a top at +5 seconds per day. It's a big watch, but it wears very well for it's large dimensions.
These aren't perfect watches however; mine came with some misalignment between the dial/bezel/chapter ring. WR Watches were willing to send me a new dial to help alleviate the misalignment if required. In the end, I didn't take them up on that offer (I didn't want to further burden them in these trying times, and there was still the risk that the new dial would also have been misaligned). The local watchmaker adjusted the chapter ring to make the misalignment less apparent (not completely gone, but better). But I have to commend WR Watches for being as helpful as they were in my email inquiries.
Die Uhr ist top verarbeitet! Das Werk läuft sehr genau! Trägt sich sehr angenehm! Indizes, Zeiger und Insert sind voll gestopft mit Leuchtmasse! Absolutes Lume Monster!
Manual winding function spoiled but customer service is good and hence 2 stars.
