I don't usually write reviews but I just had to get this out. Over the past 25 years I've owned a Citizen ecodrive diver 300 and it's rarely been removed from my wrist. It looks like it's been through the wars with scratches, scuffs and all sorts of matter worn into it during its life. It's still going strong, however I felt it appropriate to change it for something less weathered that can be worn at work (client mneetings) as well as, well, for the rest of my life. I was set on a field watch; simple, legible, accurate, tough, low/zero maintenance. I spent the last eight months concidering numerous watch brands. Premium Rolex, Tudor, IWC in excess of £7,000. Mid range Hamilton's and Marathon's and even lower-end Seiko's and Casio's. All were given considerable thought and many have been close to completing in many shopping baskets. No other watch spec came close to the Promaster Tough! As soon as it arrived a month ago, I set it to the exact second of the GMT clock. At the time of writing this review it is +/- 0 seconds which is astounding! Well done Citizen. The way it sits on my average 7" wrist is even more perfect than my beloved Citizen Diver BN0000-04H. it's understated and elegant whilst looking like it can be thrown out of a helicopter into jungle warfare. I'm 40yo now and give n the longevity and service my previous Citizen gave/is still giving me, it's safe to say this will be on my wrist for the next 25+ years and with a saphire crystal and non-scratch titanium case I would guess even longer than that! Thank you Citizen for making the perfect field watch for me.
