Seiko 5 Sports Military Automatic SNZG07J1-var-LS16 100M Men's Watch The SNZ is large, definitely larger than its predecessor SNK. It’s also better finished with slightly increased heft. It works wonderfully. An excellent choice for them who like it somewhat simple but afraid of smaller case sizes. It stands toe to toe with Swiss brands and a perfect starter watch for anyone trying to get into mechanicals completely hassle free.
