The lug profile is retained, the crown guards keep their form, and the case still has weight and definition to it. The clearest evidence is that the light wear is still visible at all, because a heavily polished case is one where the marks have been taken out along with a measurable amount of steel. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cspan\u003eThe watch is supplied on an aftermarket NATO rather than an Oyster bracelet.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 dir=\"ltr\"\u003e\u003cspan\u003eDial and Hands\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp dir=\"ltr\"\u003e\u003cspan\u003eThe dial is the original Mark 2 maxi and it is in good condition, with imperfections at six o'clock. Those marks are confined to that area and the rest of the dial is clean, with the enlarged tritium plots sitting evenly in their positions and the printing intact. The dial has not been refinished. The hands are original tritium and in good condition, aged in step with the dial. As with all tritium of this age the luminous material no longer performs, and it should be understood as a visual element rather than a working one.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\" style=\"page-break-after: avoid; margin: 18.0pt 0cm 7.0pt 0cm;\"\u003e\u003cb\u003e\u003cspan style=\"font-size: 14.0pt;\"\u003eChronometry\u003c\/span\u003e\u003c\/b\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\" style=\"margin-bottom: 9.0pt; line-height: 125%;\"\u003eThe watch was demagnetised and then tested on a Witschi WAIO, passing the tightness, demagnetisation and chronometry stages.

Amplitude averaged 258.9 degrees, from 280.5 dial up down to 239.8 at six up, a horizontal to vertical drop of 40.7 degrees, and beat error stayed between 0.1 and 0.4 milliseconds in every position. Those last two figures are the health check on a forty seven year old movement, and both read well: amplitude in the high 250s indicates a mainspring and going train doing their job well.\u003cspan\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 dir=\"ltr\"\u003e\u003cspan\u003eUse Advisory\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp dir=\"ltr\"\u003e\u003cspan\u003eThis watch is approaching fifty years old and should be treated as a vintage timepiece.  Keep it dry, and have the crown fully screwed down whenever the watch is on the wrist.\u003c\/span\u003e\u003c\/p\u003e","brand":"Crown Vintage","offers":[{"title":"Default Title","offer_id":55181948879127,"sku":"Rolex Submariner 5513 'MK2 Maxi' 40mm 1978","price":13500.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0900\/8670\/3383\/files\/rolex-submariner-5513-mk2-maxi-40mm-1978-1.jpg?v=1789251375","url":"https:\/\/crownvintage.com.au\/products\/rolex-submariner-5513-mk2-maxi-40mm-1978","provider":"Crown Vintage Watches","version":"1.0","type":"link"}
