The stainless steel case is finished in grey ion plating with a black ion plated bezel, measures 45.3 × 38.3 × 11.6mm and weighs 71 grams, with sapphire crystal carrying an anti-reflective coating, a tachymeter bezel and a resin band adjustable from 145mm to 215mm, rated to 100 metres of water resistance. The display runs three hands over three sub-dials with a date window, and the chronograph measures to 1\/20 of a second with a capacity of 59 minutes 59.95 seconds. Power is solar with no battery replacement, giving approximately five months of operation from a full charge until the hands stop, and accuracy is ±20 seconds per month.\u003c\/p\u003e\n\u003ctable class=\"cc-spec-table\"\u003e\n\u003ccaption\u003eCase \u0026amp; Build\u003c\/caption\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel Number\u003c\/td\u003e\n\u003ctd height=\"19\" width=\"129\" style=\"height: 14.5pt; width: 97pt;\"\u003eEFS-S660PB-1ADF\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCase \u0026amp; Bezel Material\u003c\/td\u003e\n\u003ctd\u003eStainless Steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSurface Treatment\u003c\/td\u003e\n\u003ctd\u003eGrey Ion Plated Case, Black Ion Plated Bezel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCase Size (L × W × H)\u003c\/td\u003e\n\u003ctd\u003e45.3 × 38.3 × 11.6 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e71g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGlass\u003c\/td\u003e\n\u003ctd\u003eSapphire Crystal with Anti-Reflective Coating\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBezel Features\u003c\/td\u003e\n\u003ctd\u003eTachymeter\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWater Resistance\u003c\/td\u003e\n\u003ctd\u003e100 Metres (10 BAR)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ctable class=\"cc-spec-table\"\u003e\n\u003ccaption\u003eDisplay\u003c\/caption\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eDisplay Type\u003c\/td\u003e\n\u003ctd\u003eAnalog\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHands\u003c\/td\u003e\n\u003ctd\u003e3 Hands (Hour, Minute, Stopwatch Seconds)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSub-Dials\u003c\/td\u003e\n\u003ctd\u003e3 (Timekeeping Seconds, Stopwatch 1\/20 Second, Stopwatch Minutes)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDate\u003c\/td\u003e\n\u003ctd\u003eDate Display\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCentre Seconds Hand\u003c\/td\u003e\n\u003ctd\u003eRed\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ctable class=\"cc-spec-table\"\u003e\n\u003ccaption\u003eChronograph \u0026amp; Power\u003c\/caption\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eStopwatch\u003c\/td\u003e\n\u003ctd\u003e1\/20 Second\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMeasuring Capacity\u003c\/td\u003e\n\u003ctd\u003e59'59.95\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMeasuring Modes\u003c\/td\u003e\n\u003ctd\u003eElapsed Time, Split Time, 1st-2nd Place Times\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Supply\u003c\/td\u003e\n\u003ctd\u003eSolar Powered\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRun Time\u003c\/td\u003e\n\u003ctd\u003eApprox. 5 Months from Full Charge\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBattery Alert\u003c\/td\u003e\n\u003ctd\u003eLow Battery Alert\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAccuracy\u003c\/td\u003e\n\u003ctd\u003e±20 Seconds Per Month\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ctable class=\"cc-spec-table\"\u003e\n\u003ccaption\u003eBand\u003c\/caption\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003eResin\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatible Band Size\u003c\/td\u003e\n\u003ctd\u003e145mm to 215mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\u003c!-- BEST MATCHED WITH --\u003e\n\u003cdiv class=\"cc-section\"\u003e\n\u003ch2\u003eBest Matched With\u003c\/h2\u003e\n\u003cul class=\"cc-tags cc-tags--dark\"\u003e\n\u003cli\u003eRacing Jacket\u003c\/li\u003e\n\u003cli\u003eBlack Tee\u003c\/li\u003e\n\u003cli\u003eTechnical Bomber\u003c\/li\u003e\n\u003cli\u003eDark Denim\u003c\/li\u003e\n\u003cli\u003eGrey Chinos\u003c\/li\u003e\n\u003cli\u003eDriving Gloves\u003c\/li\u003e\n\u003cli\u003eBlack Sneakers\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c!-- FAQ --\u003e\n\u003cdiv class=\"cc-section\"\u003e\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"cc-faq\"\u003e\n\u003cdiv class=\"cc-faq-item\"\u003e\n\u003cp class=\"cc-faq-q\"\u003eHow do I use the tachymeter?\u003c\/p\u003e\n\u003cp class=\"cc-faq-a\"\u003eStart the chronograph as you pass a known start point and stop it after covering a known distance — a kilometre or a mile. Read the number the chronograph seconds hand points to on the tachymeter scale, and that is your average speed over that distance in units per hour. It works for any repeatable measure, not just driving.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"cc-faq-item\"\u003e\n\u003cp class=\"cc-faq-q\"\u003eWhy is the chronograph seconds hand in the centre?\u003c\/p\u003e\n\u003cp class=\"cc-faq-a\"\u003eMost chronographs put running seconds in the centre and timing on a sub-dial. This one reverses that: the chronograph seconds hand sweeps the full dial while running seconds sit in a sub-dial. Timing is far easier to read across the whole face than in a 10mm register, which matters when you are glancing at it mid-activity.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"cc-faq-item\"\u003e\n\u003cp class=\"cc-faq-q\"\u003eDoes this watch ever need a battery change?\u003c\/p\u003e\n\u003cp class=\"cc-faq-a\"\u003eNo. Solar charging draws from any light source, indoor or outdoor, so there is no scheduled battery replacement. From a full charge it runs approximately five months before the hands stop, even with no further light exposure, and a low battery alert warns you before that point.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"cc-faq-item\"\u003e\n\u003cp class=\"cc-faq-q\"\u003eHow much better is sapphire than mineral glass?\u003c\/p\u003e\n\u003cp class=\"cc-faq-a\"\u003eSubstantially harder — sapphire resists scratching from keys, stone and grit that would mark mineral glass over time, which is why it is normally found further up the range. The trade-off is that a deep scratch cannot be polished out the way it sometimes can on mineral. The anti-reflective coating here also cuts glare when you read the dial at an angle.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"cc-faq-item\"\u003e\n\u003cp class=\"cc-faq-q\"\u003eIs 38.3mm too small for a chronograph?\u003c\/p\u003e\n\u003cp class=\"cc-faq-a\"\u003eIt is deliberately compact, and it is the reason to choose this model. Three-register chronographs usually need 42mm or more to lay out the sub-dials, so 38.3mm across and 45.3mm lug to lug suits wrists from roughly 15cm to 18cm properly rather than overhanging them. At 11.6mm thick and 71 grams it also clears a shirt cuff and stays light all day, which larger chronographs rarely manage.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"cc-faq-item\"\u003e\n\u003cp class=\"cc-faq-q\"\u003eCan I swim with it?\u003c\/p\u003e\n\u003cp class=\"cc-faq-a\"\u003eYes. 100-metre (10 BAR) water resistance covers swimming and snorkelling. It is not intended for diving.

The PB-1ADF is the blacked-out version — grey ion plated case, black ion plated bezel, resin band, red centre seconds hand, 71 grams. The D-1ADF runs a plain stainless steel case on a steel bracelet with a blue centre seconds hand, which reads more formal and weighs 129 grams.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"cc-faq-item\"\u003e\n\u003cp class=\"cc-faq-q\"\u003eCan the resin band be shortened?\u003c\/p\u003e\n\u003cp class=\"cc-faq-a\"\u003eThe resin band is a buckle-and-holes design covering 145mm to 215mm with no tooling required. Unlike a metal bracelet there are no links to remove, so there is no in-store sizing step — set it to the hole that fits and you are done.
