Tissot T-Gold watches

Tissot T-Gold covers the Swiss brand's gold-cased watches. Tissot was founded in Le Locle in 1853 by Charles-Félicien Tissot and his son Charles-Émile. The brand says the gold it uses is 18-carat: 75% pure gold alloyed with silver and copper. The cases here are yellow or rose gold, except the Classic, which pairs rose gold with steel.

The Excellence is a 40 mm dress watch just 5.9 mm thick, in rose or yellow gold. The Excellence Automatic is close in size at 39.8 mm but 7 mm thick, with beige or brown dials. The Vintage Chronograph moves up to 41 mm and 9.9 mm in yellow or rose gold. The Classic, at 41.5 mm in rose gold and steel, comes as an Automatic or a Quartz. The outlier is the Heritage 2009 Automatic, a 40 mm rose-gold watch with a black dial, limited to 333 pieces and, at 14.6 mm, more than twice as thick as the Excellence.

The smaller watches are in yellow gold. The Maya comes in rectangular, square and tonneau cases between 18 and 28.2 mm, all with white mother-of-pearl dials, in Classic and Trend versions. The Caliente Quartz sets diamonds in the bezel and comes on a bracelet with champagne, white or mother-of-pearl dials.

The Excellence T926.410.16.013.00 and T926.410.76.013.00 are the same silver-dial watch, one in yellow gold and one in rose gold.
