Tennis player Mirka Federer spotted wearing a Rolex

Spotted at a fashion event, Mirka Federer — former professional tennis player and longtime presence on the global luxury circuit — was photographed wearing what appears to be the Rolex Day-Date 36 reference 128345RBR in 18ct Everose gold, one of the most technically demanding and visually striking configurations Rolex offers in its flagship presidential collection.

The Day-Date 36, first introduced in 1956 as the world's first wristwatch to display the day of the week spelled out in full, has long been Rolex's prestige statement piece. The 128345RBR takes that heritage to its logical extreme: a 36mm Everose gold case houses a dial entirely paved with round brilliant diamonds, punctuated by 10 baguette-cut rainbow gemstones serving as hour markers. The bezel is set with a further ring of brilliant-cut diamonds, and the iconic President bracelet — exclusive to the Day-Date — features alternating pavé-set and polished center links. Inside beats the Calibre 3255, Rolex's in-house movement offering a 70-hour power reserve, Chronergy escapement, and Superlative Chronometer certification to ±2 seconds per day.

From a collector standpoint, the rainbow gem-set Day-Date occupies rare territory: it is simultaneously a serious horological instrument and an unambiguous statement of jewellery-grade watchmaking. The Everose gold variant — Rolex's proprietary rose gold alloy, formulated with platinum to resist fading — adds warmth that complements the multicolored stones far more naturally than white gold. Grey-market demand for rainbow-dialed Rolex pieces has remained elevated since the trend exploded circa 2018, and the Day-Date 36 in this configuration commands a significant premium over retail.

Mirka Vavrinec Federer competed professionally on the WTA Tour before a recurring foot injury ended her playing career in 2002. Since then, she has been a constant courtside presence for Roger Federer and has cultivated a refined personal style well suited to the watch's character — understated in silhouette, exceptional in detail.

At an official retail price north of $75,000 USD and grey-market valuations regularly cited around $125,000 USD, the Day-Date 36 ref. 128345RBR is not a watch one stumbles into. It is a deliberate acquisition, and Mirka Federer wears it accordingly.
