It appears to have been lightly polished at some point, which has softened the original brushed surfaces slightly, though the overall form and proportions remain crisp and well-defined. The bracelet is in very good condition and wears comfortably on the wrist. Some stretch is present, as is entirely expected given the age of the piece, and this does not detract from the overall presentation or wearability.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe dial is in excellent condition, showing no fading, spotting, or degradation to the blue surface. The handset is equally impressive, presenting cleanly with no signs of moisture damage, corrosion, or deterioration.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe movement has been tested on a Witschi timing machine and returns strong results across all measured positions. Crown up registers +1.9 s\/d, crown back +3.7 s\/d, six o'clock up +1.9 s\/d, and twelve o'clock up +11.7 s\/d, yielding a mean rate of +4.8 s\/d. Beat error is excellent throughout at 0.0 to 0.2 ms, and amplitude readings range from 287.0° to 312.7°, reflecting a movement in fine running order. The timing test was passed.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe watch has been demagnetised and has successfully passed a 5 bar water resistance pressure test. A well-preserved example that presents with honesty and wears its age gracefully.\u003c\/p\u003e","brand":"Crown Vintage","offers":[{"title":"Default Title","offer_id":52560552460567,"sku":"TUD-SUB-79090-BLUE-39MM-1991","price":10999.0,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0900\/8670\/3383\/files\/Tudor-Submariner-79090-Blue-39mm-1991-1.jpg?v=1774698790","url":"https:\/\/crownvintage.com.au\/products\/tudor-submariner-79090-blue-39mm-1991","provider":"Crown Vintage Watches","version":"1.0","type":"link"}
