Is he not just quoting red vs blue ? <| sep |> WOO WOO WOO <| sep |> rFriendlyWarsor check out the discord server <| sep |> 6 . 5 inch wrist , I would go for 38 mm dress watch or 40 mm at most . I ' m 6 . 75 and I wear a 38 mm Intramatic , 42 mm SKX 007 diver with a short lug to lug size , and a 40 mm SNZG 15 field watch . Dress watches should be worn smaller than casual or divers for most people . <| sep |> Are they waterproof ? <| sep |> Looking at the pictures , I don ' t have a great feeling about the piece . If it is from Glen LaPlaca , it is probably not reconstituted , but it is very common for commercial dealers to describe copal as amber . There are several different tests to identify copal vs amber , but the least intrusive method is UV light . Amber will fluoresce light blue , and copal generally does not fluoresce . You can also rub the piece vigorously with a clothif it becomes sticky and pliable , it is copal although amber can emit a very faint resin smell , so don ' t treat that as a smoking gun . Another popular identifier is the hotneedle test , where you take a glowingred needle and poke the piece . If it slides in readily it is copal , and if you get resistance and a smoky , charred smell it is amber . Unfortunately , this damages the piece regardless of whether it is amber or copal , so be sure to do it in an inconspicuous area , and reserve it for if the earlier tests aren ' t definitive .
