Mens round wristwatch case measuring 42mm in diameter and approximately 13.6mm thick. Equipped with a screw-down winding crown to protect the movement when servicing occurs later. Solid case back allowing access if needed though typically not user-serviceable without professional help intended however standard procedure involves this feature for some models until inspected by professionals certified IWC authorized service centers only recommended unless specific expertise available at home level tools but anyway solid base is present here too potentially although function varies manufacturer specifies it exists round shape design aligns with classic Portofino styling. Stainless steel casing material providing robustness and resistance to corrosion combined with a comfortable brown alligator leather strap secured by an elegant tang clasp for adjustability and secure fitment around the wrist circumference matching band width at 20mm. Water resistant capabilities up to depths corresponding to 30 meters or approximately 100 feet making it suitable for light splashing but not recommended for scuba diving activities where pressures exceed this level significantly especially avoiding contact with salt water which can be corrosive over time even if sealed against pressure briefly so splash resistance only rather than serious underwater operation. Chronograph function includes three sub-dials specifically designed to show elapsed seconds, minutes (up to 30), and hours simultaneously providing sporty timing features alongside the main analog display. Limited edition status restricts production strictly to 2000 individual pieces adding exclusivity value for discerning buyers collecting fine timepieces from renowned brands like IWC known since its inception in Schaffhausen Switzerland as Swiss Made indicating precision engineering heritage craftsmanship origin country importance cannot be understated here especially when combined with such a feature-rich design executed meticulously. Belongs to the established Portofino watch collection series which has defined luxury sportswatch appeal for decades maintaining brand identity consistency and customer expectations effectively translating into reliable performance aesthetic endurance functional versatility across various life situations perhaps even during sailing or boating adventures depending on water resistance level tolerance but remains fundamentally positioned within this iconic line.
