Editorial
The 16713 is the two-tone GMT-Master II, steel-and-yellow-gold case, brown/champagne 'Root Beer' bezel, the caliber 3185, produced 1988 through 2007. It shares the case and movement with the steel 16710 but in a configuration that the modern market briefly dismissed and then quietly rediscovered. The 2018 reintroduction of the two-tone 'Root Beer' (126711CHNR, with the ceramic bezel) firmed the vintage 16713 market in turn.
The 16713 launched alongside the steel 16710 in 1988, replacing the earlier two-tone 16753 'Tiger Eye' / 'Root Beer.' Production ran through 2007. Two crown-guard variants (square and rounded) span the production run. Bezel inserts shipped in factory brown/champagne ('Root Beer'), black, and a rare brown/black ('Tiger Eye').
Dial variants include 'nipple-dial' (gold-set markers, earlier production) and 'four-line' / 'two-line' depth-rating variants. The 16713 is the canonical pre-ceramic two-tone GMT-Master II.
Common things to check: gold-plating vs solid-gold (the 16713 is solid-gold center links + solid-gold case top, not plated, verify hallmarks on the case-back and the bracelet center links); bezel insert (originals fade unevenly; replacement inserts are typically too vivid, original-fade brown/champagne carries a real premium); 'nipple dial' gold-set markers (early-production examples; later-production replaced with applied gold markers), both are correct but the nipple dial is the collector preference; case (over-polishing rounds the gold on the case top, the soft gold is harder to refinish without value loss); the rehaut on a 16713 is NOT engraved; bracelet (the 78363 two-tone Oyster is correct; later 93153 are seen on late-production); 'service Root Beer' bezels are common.
