StockX, the premier online luxury marketplace, has offered watch buyers some incredible promotions in the past, but this Black Friday kicks off one of the most comprehensive deals the shop has ever offered. Rather than a promotion for a single piece or even a single brand, StockX is currently discounting prices on all watch purchases by up to ten percent with code BF2019.

The promotion runs from 12 am EST Friday, November 29 to 11:59 pm EST Monday, December 2 with one simple limitation. The 10 percent discount can be used on an unlimited number of purchases per customer, but the maximum discount amount per watch is $1,000. Other than that, there are no restrictions. Simply apply the code BF2019 at checkout and the discount will automatically apply. With that in mind, this is an excellent opportunity for any enthusiast looking to expand their collection.

The sky is really the limit with such a broad discount, but some of our favorite picks for this promotion include a $950 savings on the iconic modern Rolex Submariner, the black dial 116610. This is a serious savings for a watch that rarely gets discounted at all and remains the gold standard at which other divers are judged. For chronograph lovers, this is an opportunity to save $770 on the gorgeous and extremely popular TAG Heuer Carrera Fragment Limited Edition, one of the most faithful vintage reproductions of the past few years. If you’re in the market for understated class, this promotion could mean a discount of $520 on the stunning Grand Seiko SBGA211 “Snowflake.” With Grand Seiko’s innovative smooth-sweeping Spring Drive movement and one of the most intricately finished dials of any modern watch, this is a sleeper favorite among enthusiasts that rarely goes on sale.

If you want to take advantage of these and a wide variety of other potential bargains, you’ll need to act fast. This special Black Friday promotion will only be active through Cyber Monday. Take advantage of these deals at the StockX website.
