Hello guys,
Thanks to all for your interest,
I don't come a lot here, just because I don't have enough time to jump on several boards. But I admit I like here also and have learn lot of things.
Also thank you AllergyDoc for this review. I was not convicted as I know than here a lot of "Eagle Eyed" are flying around here... no good for me
Second, thank you Zigi for your comment about the lume process and also for your positive critics about the bezel ring and insert re-work.
You have done a good observation and you are technically right about the method I used and errors. I made 3 watches and they are prototypes. The work on the bezels has to be improved of course. The bezel rings are originally Sub design rings, and I tried to convert them in GMT bezel rings... No way to adapt gen or aftermarket ring-retaining ring-spring Rolex design on these cases.
Just to precise, all these rep "vintage" GMT Master sold by all dealers are made with a Sub 5513 background.
But what is interesting is that these rep cases are very accurate especially the crown guards design, and case thickness : gen 1675 cases are very thin
Other problem, as you pointed out, the insert has to be positionned deeper, means I should have to remove more material inside the ring or/and from the back of the insert. Its not a glue problem.
My conclusion :
no one rep has a click/pop insert system. All Rolex reps -GMT, Subs, SD, - are based on inserts glued on the bezel ring. My prototypes were modded according to basic rep vintage Rolex GMT with glued inserts.
BTW, Bezel rings were re-worked to accept oversized 1675 gen/aftermarket specified inserts. Glued.
Of course, It would be possible to profesionally machine properly the bezel ring to pop-in a gen insert,the cost would be so consequent that I would say : stop, by a gen. A gen 1675 is only 4500 euros.
The Rolex GMT master 1675 is the most difficult rep to copy, as no one Chinese maker has made an accurate case, bezel ring,insert etc.
The worse : the dial. And these "gen Singer refinished" will not fit on rep cases. Not a feet position problem but a size problem, they are anounced around 26mm diameter, rep GMT 1675 rehaut inside diameter is 27-28mm... And all these called Singer have just the name, they are just simple Singer reps.
Thanks to all to appreciate my home made 1675
