After being a non Rolexfan for about 12 years I bought my first Rolex rep a few weeks ago. As it had some issues when it arrived and not having a Rolex opener, I tried a squeezeeball without luck. So I send the watch to a friend who is a watchmaker to get it fixed. In the meantime I looked for a priceworthy alternative for the Bergeon 5700 Rolex die set which would set me back around $400.
I found this gadget.
Unfortunately the insert did not fit the Bergeon(they told me it would fit 100%) so when I got no reply after sending several emails, I decided to sand it down about 0.2 mm. The set is chinese but despite this and the sanding down of the insert and the crappy aftersales I thought its is reasonable value for money in the end. It has a very good grip on the caseback and does the job.
Die sizes are 18,5 - 20,2 - 22,5 - 26,5 - 28,3 und 29,5 mm.
