Explorer II questions

I really like the Explorer II polar with the older red 24 hour hand 16570. What was the last serial code in which the red hand was produced? Also, when was the 3186 movement started on the Exp II?

Good questions. I think there are some V serial 16570 latest. And the 3186 started showing in some Z or M serial pieces. An expert will be along shortly to verify my thoughts.

Sounds about right..

Rolex doesn't start or stop anything based on a serial number, nor does anybody know how Rolex allocates serials to different models, so actual statistics are not available to the public..

If I remember correctly, caliber 3185 went out of production in April 2007. And since there was a time lag the caliber 3186 based Explorer IIs was at ADs during the autumn/winter of 2007. They were late Z-serials. I got an M0-serial in February 2008 and it has caliber 3186. Ref 16570/3186 has been seen with serials late Z, M, V, low G and some random.

It may be worth noting that the very last white Explorer IIs had slimmer black indexes compared to the earlier, allowing for slightly more lume. But you need to know what to look for... (minor differencies as usual with Rolex from time to time).

Do a search on chrono24.com and you will find several new ones.

Good luck!

Best,

A

Edit: See Puffy's post above on the dial!

I did some research on this before I bought my 16570 last year. The 3186 movement started appearing in the Z series, but not all Z's had the 3186. Mine is a G series, but I have also seen some 16570's in the random (8 digits) series.

you MUST make sure to check out both the latest (Random) and V serial as there are IMO BIG differences in the last generation dial comparied to the second last..

see below a write up i did earlier in the year...

So it turns out that sometime after V or G, and definitely for the Random series, Rolex changed the thickness of the hour indices markers on the now discontinued etc Explorer II 167570, from thick to thin.

A guy on another forum has contacted Rolex and was advised that Rolex had made a modification to the 16570 dial recently by 'thinning out' the hour indices. This has the effect of increasing the diameter of the lume in the markers, making them appear larger at night...

Below you can see what I'm talking about

What do you guys think? Does this make sense?

Cutting down on material saves cash, it's like stripping out a car.. and why spend resources on something that is no more..

V, 2009, 16570 - THICK indices markers


Random, 2011, 16570 - THIN indicies markers

I thought i will share this with you guys and maybe you will find it interesting.


Both watches were mine. On the left we see G serial (thin markers) dial so called think frame and on the right we see Random serial with regular (thick markers) dial.

The M series 16570 I purchased in 2009, has the serial number on the rehaut and case.

A side note reference the case serial no. has T stamp indicating it is transitional. Wether this indicates the early transition from 3185 to 3186 movements or transition to SEL?

This watch has the 3186 mvt. The 16710 GMT I have is fitted with the 3185 mvt and both keep exceptionally accurate time.

If it's a 16570 with 3186 movement, the M serial # and above should get what you are looking for. Many of the trusted sellers here can probably easily source one for you.

Good luck

I thought the T stamp simply indicated solid lugs. Good intel re the hour indices; the thicker style is more pleasing at daylight but this watch would not be hurt by a bit more lume IMO

True. T-case = non-drilled through lugs. Nothing else.

But these ones like my Z-Series with thin-framed Dial or your Mk 2 LV with Mk 3 Dial should be ultra rare, shouldn´t they?

What about the rehaut engraving? Are there certain codes that are more likely to have the engraving? My preferences are: Red 24 hour hand, 3186 movement, Rehaut engraving. What serial codes do I have the best chance of finding this combination?
