Free Worldwide Insured Shipping with FedEx / Authenticity Guaranteed / 14-days Inspection Period / 1-year Warranty

With the extensive development of traveling capabilities in the 20th century, it became quite important to understand time in different locations. Anticipating the demand, an independent watchmaker named Louis Cottier invented a complication that helped to understand 24 time zones at once. That happened in 1931 and major manufacturers met his concept with interest and appreciation. Consequently, Rolex, Vacheron Constantin, and Patek Philippe - all produced same type of complication in the 1930s.

The Breitling Unitime was introduced back in 1951, but it uses the very same principle: an external ring displaying the main cities of the time, can be aligned to the 24-hour indicator in the middle of the dial. So one can look at the time (let's say 9 o'clock in the morning), and match its current location with 8 o'clock at the 24-hour indicator. All for sudden, you will be able to understand the correct time for the remaining 23 time zones. Besides world-timer complication, Breitling Unitime features date aperture at 3 o'clock and automatic movement - all packed in a very elegant 37 mm stainless steel case.

    Measuring a watch

    It is always crucial to understand the size of the watch, especially when it comes to vintage watches which are generally considered as too small in comparison with what watch industry offers today. For example, the original Patek Philippe Calatrava introduced in the 1930s was only 31 mm in diameter, while today's classic Calatrava is 39 mm. When you think about 8 mm, it doesn't seem to be a big difference, but believe it is.

    In our condition reports we normally disclose three most important parameters as follows: diameter without crown / lug-to-lug length / lug width. 

    Diameter without crown

    It is, so far, the most important measurement to understand the size of a regular round-shaped watch.It helps you to understand proportions and overall look of the watch. It is important to consider width of the bezel and color of the dial, because certain combinations may make the watch look bigger, while some other smaller. It is all very individual, however there is common understanding:

    Lug-to-lug width

    This parameter will help you to understand whether the watch is comfortable for wearing. You should compare lug-to-lug width with the width of your wrist, and if lug-to-lug width is smaller or equal, then this watch shall be comfortable.

    Lug width

    This measurement is defining what size of strap you need for the particular watch. Depending on era and manufacturer you can find watches with lug width between 14 mm and 24 mm. Most common sizes are 18 mm and 20 mm.
