The Portia collection’s signature is the small pave-crystal disc set low on the dial, and on the MK3638 it sits against solid black for the strongest possible contrast – closer to a piece of jewellery with a seconds hand than a conventional watch face. \n Case and Wrist Presence \n The case is 37mm in polished stainless steel, a size that carries weight on the wrist without crowding a smaller frame. The matching link bracelet keeps the whole watch in the same silver tone from lug to clasp. \n Dial and Legibility \n Against the black dial, slim polished batons mark the hours and the Michael Kors wordmark sits just below twelve. The lower half of the dial is given over to a crystal-paved sub-disc that carries a slim running-seconds hand – it is decorative first, functional second, and it is the detail that identifies this as a Portia. \n Movement and Functions \n A quartz movement drives the watch, needing nothing beyond an occasional battery change to keep accurate time. It is a time-only piece; the crystal disc carries the seconds rather than a date or any other complication. \n Strap, Clasp and Fit \n The bracelet is stainless steel in polished links matching the case, giving the whole watch a uniform, cohesive look on the wrist. \n Who This Watch Suits \n Black and steel is the most versatile combination Michael Kors makes in this size – it goes as easily with denim as with tailoring, and the crystal disc gives it enough presence to wear on its own without other jewellery. \n Care and Maintenance \n Wipe the case and bracelet with a soft cloth after wear to keep the polished finish free of fingerprints, and keep the crystal-set disc away from perfume and lotion, which dull the stones over time. Have the battery replaced by a watchmaker to keep the case seal intact. \n About the Brand \n Portia is one of Michael Kors’ longer-running dress-watch lines, built around this same combination of a clean dial and one deliberately decorative detail rather than an entire dial’s worth of pave. \n Technical Specifications \n Attribute Specification \n Brand Michael Kors \n Collection Portia \n Model MK3638 \n Gender Women’s \n Case Diameter 37mm \n Case Material Stainless steel \n Case Finish Polished \n Dial Colour Black \n Movement Quartz \n Bracelet Stainless steel \n \n Buying With Confidence \n The MK3638 carries a 24-month international manufacturer’s warranty on the movement (battery and normal wear excluded), and ships new and unworn in its original box with the manufacturer’s paperwork.
