uxcelluxcell Watch Crown Winder Tool 5-6mm Manual Mechanical Winding Instrument Silver Stainless Steel Watch Repair Helper

It works as expected. Saves my fingertips.

It does what it is supposed do along with saving my finger & thumb. It took quite a while to advance the date by 29 days.

I bought this watch winder because I've accumulated a lot of mechanical watches over the years and I have a hard time winding some of them because my fingers are getting older, because some of the crowns are worn and slippery, and because some the watches were just designed so they are hard to wind.However, before the review, I'll share some useful info on which size winder to buy because I could not find this information anywhere in the description or reviews and I wound up taking a guess, which fortunately worked out for me. Almost all of the crowns that I would use this winder on measure about 5mm in diameter, with some going up to 6mm. I took a guess and bought the winder that is marked 4.0-5.0. This means that the minimum crown this winder will work with is 4.0mm in diameter. However, the winder head expands considerably and will fit crowns almost up to 6mm. So rather then having a 1mm range which the markings imply, this winder, and I presume the others in the family, have a range of about 1mm larger then what is marked.Regarding the product review, first the good.- The winder is very well made. Solid steel, well finished, (almost) well fitted parts. This winder will outlast me.- Simple to use one handed. Hold the winder between thumb and middle finger against the crown, push in the button on the end with the index finger to expand the collet, and slip the expanded collet over the crown.Now the bad- As others have mentioned, the button/collet spring is VERY strong. My wife with arthritic fingers cannot use this tool one handed as described above. It takes more then just her index finger to push the button and she must adjust her technique. But on the other hand (no pun intended) the strong spring is probably needed in order to grip the small sometimes worn crowns firmly enough to wind the watch without slipping, so it's a tradeoff you need to be aware of when purchasing.Overall this is a quality made, required tool for anyone owning an old or modern windup watch.

If you've ever had trouble winding a mechanical watch this is your tool. Best available in several sizes to fit the crown (winder size). A must-have in a varied size of 5mm-6mm in one tool. This size fits the larger crowns like a Rolex, etc.

Part of my job involves putting batteries in watches. It's not uncommon for each of us to do 6-8 a day & there are 3 or 4 of us working at any given time. Many day/date watches allow the date to be set in either direction which means that to set the day you have to advance the hands around twice for each day. Try that with your fingers if today is Monday & the watch shows Tuesday. Crown winders give you a much bigger surface to turn. The only problem with this version is it only fits crowns 5-6mm in diameter. A lot of ladies watches have a crown that is only 4mm in diameter. I'll keep this one but, I've already ordered a set that should work with any watch we see.

I have been using it for a few months now, and it is much better than using just my fingers to wind my watch. I would recommend it.

Does a good job for a watch I can't wind by hand.

Some crowns are just hard to wind, this makes life simpler!
