Seiko Samurai Mod — the angular diver donor

The Samurai owes its nickname to the sharply faceted case whose crisp surfaces recall a blade. As a rugged 200 m diver from the SRPB/SRPF line with a current 4R movement, it is a distinctive donor base for builds meant to stand apart from the round SKX silhouette.
