A Decade-Old Design Gem: Tissot PRS 516 T100.428.16.051.00

Rediscovering the Tissot PRS 516

The Tissot PRS 516 T100.428.16.051.00 is a timepiece that captures the spirit of motorsport with a design that feels both nostalgic and refreshingly original. As a watch enthusiast with a worn-out Tissot Le Locle, I sought something more youthful and sporty yet still suitable for formal occasions. After much deliberation, the PRS 516 stood out—not only for its racing pedigree but also for its unique aesthetic.

A Design That Defies Its Price Point

What immediately drew me to this model is its unconventional seconds display: instead of a central seconds hand, three sub-dials at 3, 6, and 9 o'clock each track a portion of the seconds. This layout, combined with layered hands and a raised bezel with applied indices, creates a sense of depth rarely seen in watches under ,000. The official photos don't do it justice—in person, the dial feels intricate and premium.

The Movement Question: Powermatic 80 vs. Older Calibers

Most current Tissot mechanicals, including the PRS 516, use the Powermatic 80 (P80) movement. While it offers an 80-hour power reserve, its plastic escapement wheel and pallet fork can wear out prematurely—my family member's watch needed service within three years. That's why I opted for this older model, which houses the ETA 2815-2 (or similar) movement, known for its robustness and easier serviceability.

Wearing Experience and Practical Notes

On the wrist, the 42mm case and 14mm thickness feel substantial yet comfortable, especially on my 19.5cm wrist. The flat caseback improves ergonomics, making it hug the wrist better than the Le Locle. The original leather strap had deteriorated, so I swapped it for a steel bracelet—it's heavy, but it balances the watch's heft. The lume is modest but legible, and the see-through caseback reveals a steering wheel-shaped support, a nod to the racing theme.

Buying Tips: Finding New Old Stock

If you're hunting for a new PRS 516 T100.428, be prepared to look beyond mainstream markets. I sourced mine from a Japanese seller via online shopping. It came with a paper warranty card dated on the purchase day, and the seller included English instructions—a thoughtful touch. The price was about 60% of the Chinese retail, reflecting its age. Availability is scarce now, so patience is key.

Final Thoughts

The PRS 516 T100.428 is more than a watch; it's a piece of design history that offers exceptional value. Its unique seconds display and build quality make it a standout in any collection. If you appreciate quirky, well-made timepieces, this one is worth seeking out.
