Thanks for the write up KJ. Very informative and helpful as usual.

Question for you: how do you think this case compares to the viet cases which have been the go-to for franken 16710s up till now? This case looks pretty good and the viet cases are almost 2x in price…
I've not had a Viet case in hand bro so I can't compare firsthand. I think this one has great quality of production at an attractive price. It needs a little tweaking as I've pointed out but the few minor issues are all easily remedied. Some modding and aging should be expected to be needed on any vintage case to personalize it and make it look period correct and authentic.

Anyone else ordered these bezels before and can comment on them? I only knew of wso and ST!
I was asking the same question like 6months ago (or so) but they seem new to everyone here.

Pics are fine but you never know until you have it in your hands. To me it's great they put all the specs in the product sheet so if one has the sizing of a gen bezel with all the diameters (ID, OD etc) maybe can compare.

Plus (but this is a plus only if you're in EU) you avoid all the extra fees due to customs that you would have with ST..

@KJ2020 , sorry if I missed your post, but a comparison between this ebay case and this BPF watch that you have would be fantastic.


I just happened to have the same BPF 16710 and its case wasn't too shabby. The only setbacks were that it was for 2824 (which I can fix) and that it may not be able to accommodate gen 16710 bezel assembly (but again, I am building a 16570).

BP made a few 16710 variants. The predominant one has a 2836 ICHS, and it's cheaper sibling has the 2813 (DG3804) ICHS. These are the most common ones ppl have.

BP also made a mod DG3804 CHS which was unreliable, unpopular and wasn't in production or on TD lists very long. Recently they released an SA3186 version, another timebomb movement that no one should buy unless planning to upgrade to a VR.

So in all likelihood you have the 2836 ICHS whose case is not perfectly suited for a 3186. The crown sits too low and some modding is needed to make the 3186 fit in the case. It has the wire clip bezel which is smaller in OD than gen, so it wont take a gen bezel or insert. To convert to a gen bezel, some metal reworking of the outside of the rehaut is needed. The crystal is not gen-spec, it has a straight-edge 30.5mm OD with a very short height and skinny gasket. Gen crystal has a stair-step edge, at 29.5mm OD where the gasket fits. I have fitted a few with gen-spec crystals by using two gaskets but this is not a technique for a Franken. Another HUGE drawback to all the BPs is the very wide chamfers which are very difficult to rework.

In summary, the EBAY case shape is leaps and bounds ahead of the BP, there really is no need to even consider BP for a Franken GMT

Since you are making a 16570, you should have a look at the thread below. This member has done some upgrades to a BP 16570, but this BP model has some differences to the BP 16710.

Well darn it. @KJ2020 you have now driven me to go forth and build that 16570 I have been dreaming of for years ( thanks for that btw, I have been procrastinating). Now I just need to source some parts. Sigh, yet another project to get down.

many thanks for the awesome review and updates Sir.

I just finished my 16750 build.

- Gen insert, hands (except hour hand), dial and crystal with AR+LEC
- ST bezel assembly
- Rep crown + tube
- VR3186
- Raffles Bracelet

The ST retaining ring went on SUPER tight, like uncomfortably tight to my liking compared to other cases I've worked on. However, all that being said this watch is absolutely superb and a joy to wear. 100% recommend this case set.

Just finished my explorer build with this case and the gen bezel wouldn’t go on all the way with a cheap press. Had to put it in a vice (which went on super easy) It’s going to be a struggle to remove it if I need to.
I am really pleased with the results.



Gen dial
Gen hands
Gen bezel
Gen crown
BP crown tube from my explorer I so has a small gap between crown and case (gen crown tube is in the mail)
Ginault crystal I had lying around- need to replace with gen.
2.75 crystal gasket
Stock cheap datewheel, would be nice to replace with gen but a pain to remove hands again.

Quickly tried out a couple bracelets. A BP explorer bracelet and an Italian bracelet. Neither fit great at first. The ginault bracelet (no pic) seemed to fit better. I will be test a bit more when I have more patience.

I'm still waiting on some parts for mine but I wanted to mention something I found while test fitting some pieces together.

The factory brushing doesn't go up quite close enough to the outer rehaut to be covered by the bezel. This means narrow unbrushed strips will be visible outside of the bezel circumference. This is more pronounced on a 16570, as that bezel is only 39mm while the GMT bezel is 40mm OD.

It's a easy fix - wrap some 320 - 400 grit paper over a sanding stick or similar and blend the areas together. Finish with some Scotch brite or other brushing pad.

Then you can cut some chamfers.
