Eilux, a Hong Kong based company was formerly called Everwell Instruments. They hold many patent rights to their design and watch winder mechanisms. No matter how hard they try, this Made-in-China product has now multiple replicas floating in the market.
All Eilux Watch Winders features individual winding heads which I favor most. This ensures each individual watch gets the 900 TPD in the correct winding direction. Alas, if only Eilux could provide users with a choice of TPDs, say a low of 600TPD and a high of 900TPD.
5) Noise Level
There are two kinds of noise I’m usually weary about in a watch winder. The first being mechanical noise. Eilux deploys an expensive and primitive approach when it comes to noise-control. They have mounted the motors far away from the front panel using molded plastic parts. I’ll explain more in PART 2. However, it works smoothly and silently, as it should, during operations. My method of measuring noise of a watch winder is with its front cover closed and from a distance of an arm’s length.
The next type of noise I would test for is the electrical noise. A very simple test can be done by placing this unit next to a television set or the radio. Electrical noise is detected when the screen goes fuzzy or the audio sounds like a motor-boat. This unit displays none of these.
6) Performance – Turns per Day
Switching it ON, I proceed to time the motor’s RPM. This unit turns at 6.5RPM. From here, I could then calculate the actual estimated TPD as printed in their user manual.
EW3500 has its winding sequence as follow: -
a) Bidirectional Setting
A winding cup (motor) turns CW 118 seconds, pause 2 seconds, turns CCW 118 seconds, pause 2 seconds… This will be repeated 36 times in a day, giving the CW and CCW directions 460.19 turns each. This adds up to 920.38TPD which is close to its stated 900TPD setting.
b) Unidirectional Setting
In this setting, the motor turns CW or CCW for 24 minutes and then rest for 216 minutes, repeating 6 times resulting in 936TPD per direction.
(Note: - Please meet me if you are interested in the calculation.)
This confirms that their TPD provided is truly close at 900 unlike other winders in the market where they simply ‘under-declare’ the amount of turns provided by their winders.
For those of you with Rolex watches, please set it to a bidirectional setting as most rollies require up to only 800TPD while Daytona’s require up to 900 TPD. Same goes for Breitling and AP.
Do refer to Eilux website for a list of individual watches winding requirements.
7) Winding Programs
As I've mentioned, Eilux only provides selection for winding direction. The TPD is factory preset to 900TPD. One important thing to note... always switch off the unit before changing directions. The program needs to be "hard" reset, just like a boot-up in computers. If you change directions while the unit is still ON, the winding sequence will still follow the last set program. Lastly, its also good for the motor's gearing system. Just as an example, when we're driving our car forward we don't immediately change to a reverse gear!
On the down-side, I don’t think Eilux would be suitable for thick bulky watches due to the distance of the plexi-glass cover to the winding cups when closed. Another set-back is the winding cups not able to accept buckles wider than 37mm. Hope someone with a wide watch buckle and an Eilux winder could confirm this.
But overall, Eilux has a truly well-engineered professional watch winder any watch aficionado would want to own...
