| The 1960s was a golden age for the development of automatic timepieces, and countless classic models were born during this historical period, as was the case with the Tiggo Jacaraera series. With its elegant appearance and reliable performance, the Carlisla series has been popular since its launch in 1963 and is loved by many professional racing drivers. In 2023, marking the 60th anniversary of the launch of the Carlisla series, the brand Tag Heuer replica watches has launched several commemorative works and a brand new self-produced movement, the TH20-00 model. The more complete performance of this movement is expected to replace the widely used Heuer 02 model and become the main force of brand timepieces in the future. In fact, looking at the development of Taigehaoya's self-produced timing movements, I would prefer to call this process a "three-step process".
As early as the 1960s, Haoya (before joining TAG Group) began the research and development of timing movements. The first manual chain up movement, Cal.11, has a vibration frequency of 19800VPH and a dynamic storage time of 42 hours. It has been installed in series such as Carlisla, Monaco, and Autavia. The movement subsequently underwent a minor modification, such as using a lower torque spring Rolex replica watches uk box and changing the sliding small gear to steel.
The Cal.12 movement was released in 1971, optimized with stronger spring springs, gear trains, and cycloids. The Cal.12 movement has a vibration frequency of 21600VPH, and the timing hammer has been improved to enhance seismic resistance. Subsequently, derivative models Cal.14 and Cal.15 were successively introduced, marking the first stage of the brand's self-produced timing movements.
After the "Quartz Crisis" in the 1970s, Hoya timepieces mostly adopted an external movement plan based on ETA/Valjoux 7750, until the release of the Cal.1887 movement in 2009, which broke this situation. The 1887 movement adopts guide column wheels and horizontal clutch, with a diameter of 29.3mm, a vibration frequency of 28800VPH, and dynamic storage for 50 hours. The functional Cartier fake watches uk discs of this movement are distributed between 12-9-6 o'clock positions, with the visual center of gravity leaning towards the left. From a structural perspective, it has a certain structural connection with the Seiko Cal.6S37 movement, such as using the "magic bar" automatic chain up system (referred to as the "double locking bar" by Tegehauer).
The Heuer 01 movement, released in 2015, is considered the stable version and final form of the Cal.1887 movement. These two movements can be seen as the "second stage" of Taigehaoya's self-produced timing Omega replica watches uk movements.
