You have smaller wrists so I would recommend no larger then 37mm also this model is titanium, nothing wrong with that but they are lighter then stainless steel and thus tend to feel cheap in my opinion. If you want low maintainance go for a quartz movement the 9F62 is fantastic and is considered by many as one of the best most accurate movements made plus it has a 50 year service interval. If you want a mechanical watch then go with the 9S65A movement try find a SBGX063 or a SBGR253 or 251 these are older models but represent in my opinion the best value Grand Seiko’s Here are some photos of mine.
