Does Hublot use ETA movements?
Hublot is currently making in-house movements for some of their higher-end tourbillon movements and will follow up with a more basic movement to fill the spot currently occupied by movements from ETA . Hublot has done so well with ETA movements until now, so why ruin a good thing?
Can you replace the movement in a watch?
You can replace a mechanical movement with a quartz movement or change a quartz movement with an inexpensive generic or factory direct movement without problems.
How do you get a watch off your wrist?
Place your watch into the holder or foam piece so that you can see the top of the pin. Use the pushpin tool and the hammer to gently tap the pin until it emerges from the other side. Use your fingers or a small set of pliers to remove the pin gently.
How long should a quartz movement last?
Longevity: A quartz watch can last the user for 20 – 30 years, as the electronic components of the watch will eventually wear out. A well-maintained mechanical watch will outlive the original purchaser. High-end mechanical watches can be heirloom pieces, passed down from generation to generation.
How do you remove a stem and crown from a watch?
Grip the pin vise securely in one hand and the crown at the end of the stem in your other. Then in one quick motion, turn the pin vise one direction and the watch crown in the opposite direction to break the seal between the stem and the watch crown.
What is a 7750 watch movement?
First of all, the 7750 is a mechanical, manual-wind movement that uses a three-plane cam system to operate its mechanisms. The standard 7750 has subdials at the 6, 9, and 12 o’clock positions. The original Valjoux 7750 units contained 17 jewels, while most modern ETA 7750 variants hold 25 jewels, which allows for less wear and tear.
What is a Valjoux 7750?
On Caliber Corner, we usually refer the these movements as ETA/Valjoux caliber 7750. Some watch brands refuse to call it the ETA 7750 and will list the movement as a Valjoux 7750 in their specs. Valjoux (the name comes from Vallée de Joux) joined Ebauches SA (ESA) in 1944.
Why is the hand not lining up on my 7750 watch?
Unlike quartz powered chronograph movements, mechanical watches do not have the luxury of using a reset sequence to get the chronograph hand to line up to 12:00. If your caliber 7750 powered watch has a hand that is not lining up, it could be a mechanical problem and should be inspected by a professional watchmaker.
What happens if you put a gear train on a 7750?
With the way the gear train is set up on the 7750, this could add extra and unnecessary wear and tear. Additionally, by doing so your watch will experience a change in amplitude, leading to a loss of power reserve and accuracy. The ETA/Valjoux in the photo below is from a Kobold Phantom Chronograph watch.
