The term "number one watch" in this context refers to the very first watch produced in a limited series of watches. In the case of Vostok-Europe, they have decided to manufacture only 3000 units of a particular watch model. Being the "number one" means it is the first unit produced out of the 3000.

This status adds significant collectible value for several reasons:

1. Exclusivity: Since there are only 3000 units, owning any watch from this series is special. However, the first one is often seen as the most desirable because it marks the beginning of the series.

2. Historical Significance: The first watch in a series often represents the realization of the design, engineering, and conceptual efforts. It's like owning a piece of the brand's history.

3. Potential Value Increase: Limited edition items, especially the first in the series, can appreciate in value over time, especially if the brand or model gains prestige.

4. Unique Identity: Each watch in such a limited series often has its own unique number. Owning number 1 out of 3000 is a notable distinction, as it is a tangible symbol of the rarity of the item.

Collectors and watch enthusiasts often seek such unique pieces not only for their functional value but also for their historical, aesthetic, and potential investment values.
