The Citizen BM6400-18E is a
pretty sleek Eco drive watch. It has a canvas strap and a stainless steel case.
Overall, it’s a very photogenic watch whose beauty is really in its basic
simplicity: there are no bells and whistles here; it’s just a timepiece. The
only add on you get is a single date calendar (minus the day). The numbers are
large and luminous, and can be seen quite clearly in the dark. Because it’s an
Eco-Drive, it doesn’t need winding and will go on indefinitely – until you
starve it of sunlight. Even at that, the manufacturers boast it will still
operate for at least six months when placed in darkness.
This watch is actually an
updated version of what was commonly referred to as ‘the Ray Mears’ watch – the Citizen Promaster PMU56-2371. Whereas that one retailed at between €300-€400 and had a
Titanium case which came with a choice of black canvas or Titanium strap, the
BM6400-18E costs half as much (even less if you happen upon it in a sale) and
comes with a stainless steel case. They look almost the same except for some
notable differences, which can be seen in the comparison photos below.

Unfortunately, though, the Citizen Promaster PMU56-2371 is not
being made anymore and is extremely rare to come by. If you do, chances are you
will be paying a hefty price for that rarity. However, there is one big
difference, which makes me prefer the cheaper updated BM6400-18E model: the
numbers are actually moulded on the face/dial whereas they just seem to be painted
onto the older Ray Mears version.
The closest watch available would be the Citizen Royal Marine Commando BN0110-06E (see above), which is also made of Titanium, and has the same overall design and bulky appearance, but you can expect to pay the same amount for it as the earlier Ray Mears version. For price alone, you can't go wrong with the BM6400-18E. And as an extra bonus you also don't get the 'Royal Marine Commando' label on the face, which for watch purists, is a bit of a no-no.

The strap of the BM6400-18E is made of black canvass and
while it looks better than the wretched green canvas straps of several Citizen
releases, it still sufferers from the same basic problem: the holes always
manage to just barely miss your ideal wrist size, so what you’re left with is a
watch you will either wear slightly too tight or quite lose. The steel enforced
buckle wholes, while cool looking, make it impossible to create an extra hole
should you need it. It’s fair to say most buyers of this watch will opt for
putting on a new strap.
Another minor quip would be the crown: it seems (at least
on my version) that place where the winder sits in wasn’t made wide enough to accommodate
it, so you have the effect that it always looks like it’s not pushed properly
into place. (NB: I have recently learned this is not the case. Apparently a lot of these watches are being delivered with the winder/crown pulled out, giving the impression of an error in workmanship. Not so. If you look carefully, there are THREADS where the crown is pushed in; only you have to push and twist to set it properly into place. I found this out by complete accident after many weeks of risking damaging the crown/winder by leaving it in the 'out' position.)
Overall, though, it’s a beautiful and simple
watch that is a very accurate timekeeper – losing bare seconds over a two-week
period. Those after the extremely rare Citizen
Promaster PMU56-2371 could do a lot worse than to give up the chase
and splash out on its cheaper, stainless steel successor instead.
