Rolex Explorer II vs monte SPIGA

For the discerning horologophile, just how close is the upstart Rolex to presenting a serious challenge to the classic monte SPIGA MOS6170 ?

Let us cast a critical eye upon the established segment leader:

As we can see, the incumbent presents a clean, modern face and classic lines. Yes, that rehaut is indeed engraved.

Could Rolex, who for those that might not have heard of the brand, are an ambitious Swiss-based outfit concerned mainly with sports marketing but branching into manufacturing, present a credible response ?

Rolex offer this interesting Explorer II model. As we can see, it draws significant influence from the aforementioned monte SPIGA :

It’s worth pointing out Rolex’s stubborn resiliency to improve too. They previously released a lesser model, pictured here :

This was also called the Explorer II but it was smaller than the monte SPIGA and featured the wrong colour 24 hour hand. Both deficiencies have been corrected in the current Explorer II.

The match is thus well truly on. Let the battle commence.


Both the monte SPIGA and the Rolex Explorer II offer traditional 12-hour time and date plus an auxiliary 24 hour hand for tracking a second time zone. Though it should be mentioned that the very first Rolex Explorer II offered a 24 hour hand that indicated simply day or night. Rolex were reduced to marketing the watch to the spelunking community. A somewhat limited and niche sector populated by bearded people who enjoy spending their leisure time getting lost in damp caves.

Later revisions, including the current one, allow the 12 hour hand to be independently set. Thus providing a more useful feature for the frequent traveller. The market was expanded to include those whose wardrobes excluded green boiler suits.

The monte SPIGA, as the with the current Rolex, offers an independently adjustable 12-hour hand. Unlike the Rolex, the monte SPIGA also offers a quickset date for ease of use.

On functionality then, after a few false starts from Rolex, I generously award :

Rolex 3 points, monte SPIGA 5 points.


Clearly disadvantaged, the Rolex wristwatch can claim only scant history dating back to the Europe of the early 20th century. Even Asian upstart Seiko, a mass manufacturer of popular cheap timepieces and plastic kitchen clocks, predates it by decades. The monte SPIGA is made in China. The nation that, it need hardly be reminded, invented the mechanical clock escapement in the 8th century. With typical precision, this was perfect preparation for their invention of gunpowder and rockets in the 9th century.  Scholars agree it is therefore highly likely that the first fireworks demonstration that started exactly on time was during the T’ang dynasty. Long before the Swiss tried to claim punctuality as their own. A historical outrage to which a dispassionate observer might be heard to retort, “Cuckoo clocks!”

To be fair to newcomer Rolex, it has valiantly tried to attach some history and provenance, not least in the very name “Explorer”. A reference to the claim that Sir Edmund Hillary carried a Rolex to the summit of Everest. This may be true, but he wore a Smiths watch. He certainly carried a lot of things. Including for example, a fetchingly-designed tea towel, worn as a hat.

While an impressive feat of mountaineering, this does not definitively prove the tea towel has legendary endurance. Equally, Mt Everest is in Nepal bordering China, not Switzerland. The Swiss can only offer Mt Rosa, which is half the height of Everest and no one cares who climbed it first or indeed ever.

Rolex might wish to reconsider this explorer association. A touch grasping.  Perhaps the Rolex “Ballast” or “Backup To My Smiths” might be more appropriate.

On Provenance then, our investigations lead to a score of Rolex 1 point, monte SPIGA 5 points


A tough fight this one. Both watches are made from solid steel cases, water resistant to 100m, with a steel bracelet and solid end links. The monte SPIGA shown here:


Both should be tough enough to survive all but the most feisty boardroom meetings. There are some important differentiators though. The Rolex punches hard with a sapphire crystal, the monte SPIGA parries with a “hardness glass” according to its caseback engraving. The Rolex has a screw-down crown. The monte SPIGA achieves its 100m rating without such a facility. Meaning that unlike its competitor, it is impossible to accidentally leave it unscrewed and vulnerable.

It is when we look inside the watch that the real killer blow is landed.  The Rolex uses a mechanical movement, powered by a spring, automatically wound by the movement of the wearer’s wrist or manually via the crown. Fully charged as such, it promises about 2 days of power and an accuracy of around 2 minutes a month.

The monte SPIGA uses an electronic movement, the hands powered by a motor driven by a battery and timed using the oscillations of a quartz crystal. It offers about 2 years of power and an accuracy of around 2 minutes a year.

Further research into the apparent poor performance of the challenger was conducted. According to its manufacturer, it uses all sorts of “advanced” materials and techniques but in essence, a spring is still a spring and the figures prove the point. Inside the Rolex it is as advanced as a bakelite dial phone.

The monte SPIGA by contrast, is an iPhone. Those legacy Rolex gears and springs require regular maintenance to be conducted by the manufacturer, at a cost of $500 or so every 5 years. The monte SPIGA uses reliable technology, requiring a simple $5 battery change achievable by any local outlet, every 2 years.

Rolex’s wilful negligence of progress, while dressing it in high-performance language, is presenting mutton as lamb. I can only assume that Rolex choose not to use a fashionable “display back” in order to hide this sorry deception from the potential purchaser.

I understand that, the world being what it is and tolerance being at all-time high, there are some who profess to prefer such anachronisms. I think we can proceed in confidence knowing that they must be either perverts or the sort of chap who frequents those seedy watch forums. Probably enjoys changing his own straps, if you know what I mean.

We shall move on swiftly.

On Performance, we arrive at Rolex 1 point, monte SPIGA 5 points.


Predictably perhaps, the monte SPIGA is challenged here. While it offers higher performance, lower running costs, more features and improved ease of use, it has arguably priced itself out of the intended market. The monte SPIGA is available from dealers boxed, new, and guaranteed for a year for $60. Hang-tags and stickers included.

This is far beyond the reach of most luxury sports watch buyers, many of whom struggle to pay less than $1000 for a metal bracelet. Rolex are right in the sweet spot, by contrast, asking a far more reassuring $8100. It’s a devastating response to the monte SPIGA, and Rolex wins this round easily.

On Value, Rolex gains 5 much needed points. The monte SPIGA strikes out with zero.


Rolex should be congratulated for staying the course and improving their challenger over the years until it represents at least some serious competition. Certainly, it has aced the value proposition. Overall though, the incumbent demonstrates why it is such a reference. On total points, it scores 15 points to Rolex’s 10.

Result: An easy win for the full monte.

    You’re exactly right – I bought a Rolex GMT-Master in 1967, when I was 18, when James Bond was cool, when I loved SCUBA and when navigation was forced to use the best possible mechanical time pieces. – But for celestial navigation, a four second time error translates to a one-mile navigational mistake. So, when quartz watches came into being I spurned my Rolex, first for a cheap quartz alarm clock, then for Seiko and Casio quartz watches. – I admire the stalwart mentality of making the best possible mechanical time pieces, but does the world really need millions of them manufactured every year?
    A Rolex IS nice jewelry, and it’s a nice piece of history, but it’s not of interest for someone who has a serious need for accurate time keeping.
