Big News for the replica Tudor and its chronometers

The story of the replica Tudor usually revolves around its sibling status to the replica Rolex, but since entering the UK market a couple of years ago, it’s been strident about its role in both developing the iconic ‘tool watch’, and for supporting those adventurers, spiritual or otherwise, who’ve decided to wear its robust and lately highly collectible pieces. 
The choice of Lady Gaga, then, fits with a brand profile that’s moving away from equipping explorers and other items, and joining a broader discussion around what does and doesn’t fit the ‘status quo’.
With her six Grammys, Golden Globe and 30m albums sold, Lady Gaga has clearly prospered in the mainstream whilst greatly abstaining from its cookie-cutter standards; ditto Tudor replica, which has helped bring fabric straps a lot recently and ‘neo-vintage’ designs back to the horological fore. 
Now we have another question, why are some fake watches referred to as chronometers?
The term chronometer (which is simply means “time measurer” in Latin) can only be used if the movement in question has been tested and certified by an independent authority. Although there are many of these bodies around the world, in practical terms this normally means the Swiss Official Chronometer Testing Institute. The institute tests the movements submitted to it for their accuracy over a period of 15 days: the first ten at room temperature and for the last five at a range of different temperatures. The measured timekeeping deviations must lie within pre-defined tolerances, usually of -4/+6 seconds per day, or a precision of 99.99%, the most accurate mechanical movement can be. If this is the case, then a Swiss Official Chronometer certificate will be issued for the movement and as such is a mark of quality. The term chronometer was originally coined by Yorkshire clockmaker Jeremy Thacker in the early 18th century in his unsuccessful quest to build a clock accurate enough for marine navigation – the problem being how to deny the effects of the motion of the ship. This was important for marine safety and exploration and so of vital concern to the British as the pre-eminent naval power of the age. Self-educated carpenter John Harrison then took up the challenge was ultimately and one of his chronometer designs was used by Captain Cook used his during his second and third voyages. Harrison made himself the equivalent of a multi-millionaire owing to his efforts – and helped the British Empire to dominate the world’s oceans for the next century.
