Most Collectible watch for investment within 1 M HKD

 Some of the most collectible watches that could be good for investment within a $1 million HKD budget (around $130,000 USD) include: 

• Rolex Daytona with Paul Newman dial. Vintage Daytonas from the 1960s/70s with the distinctive Paul Newman dial are hugely sought after and prices have skyrocketed. Even with the high prices, they are seen as solid investments that will likely continue to rise over time due to their legendary status. 

• Patek Philippe Calatrava reference 96. The reference 96 from the 1930s is one of the most iconic simple dress watches ever made. In solid gold, it epitomizes Patek's understated elegance and would be a prestigious piece to own, holding its value very well. 

• Audemars Piguet Royal Oak "Jumbo". The original large-size Royal Oak from 1972 is the most coveted version of this luxury sports watch icon. As the watch that launched the genre, an early, well-preserved Royal Oak "Jumbo" would be a very safe and lucrative investment due to its importance and popularity. 

• Omega Speedmaster Professional "Moonwatch". The original Speedmaster Professional worn during the Apollo moon missions has legendary status. As one of the most significant watches ever made, a vintage "Moonwatch" in good condition could be expected to rise substantially in value over the long term, despite already high prices. It represents a piece of history as well as a prestigious watch. 

In general, the most collectible watches are landmark models from the most prestigious brands, in original or near-original condition. While nothing is risk-free, such historically and culturally significant watches have a good chance to steadily gain value over time due to their enduring appeal and limited supply of good-condition vintage pieces. Of course, tastes can change and there is always uncertainty, but iconic watches tend to hold up as relatively safe investments.
