Citizen BM7170-53L Review – Eco-Drive Titanium Watch

Being a bit more knowledgeable in watches, my cousin recently asked me to take a look at the BM7170-53L timepiece from Citizen.

He was planning to replace his aging unit and was considering buying this watch.

I didn’t own one, so I had to dig up some information for him.

And to my surprise, that timepiece was a very decent one!

So, in this short Citizen BM7170-53L review, I’ll talk about the key features of this wristwatch that I think you will want to know the most.

Citizen Men's Eco-Drive Titanium Watch with Date, BM7170-53L
  • Round watch in titanium featuring blue dial with honeycomb pattern at center, date display at 3 o'clock, and luminous...
  • 43 mm titanium case with antireflective-sapphire dial window
  • Japanese-quartz movement with analog display and 180-day power reserve

Tough and Durable Titanium

The moment I saw that the watch is made from titanium, I knew it was worth buying.

Titanium, as you may already know, is among the toughest materials.

It’s tougher than the likes of steel, aluminum, and carbon fiber.

According to the manufacturer, its hardness rating 5 times that of stainless steel.

However, it is about 40% lighter in weight.

Wearing the watch for long periods will therefore not be a problem.

Safe and Hypo-allergenic

Citizen BM7170-53L review

My cousin has very sensitive skin.

In fact, he hardly wears any jewelry.

A little bite from an insect or bug will see rashes and redness develop all over his body.

I saw it once and couldn’t believe my eyes!

And regular stainless steel is known to cause allergic reactions.

However, with super titanium, chances of the allergies or side effects taking place are very slim.

This is because it is hypoallergenic.

This was the other reason I was in the opinion that this would be a good choice for the guy.

Eco-Drive Needs No Battery

One thing that Citizen stands out for is the Eco-Drive technology.

This is a revolutionary technology that transforms both artificial and natural light into electric energy.

And since my cousin works outdoors, the watch will be exposed to light for longer periods.

The manufacturer claims that a full charge will power the watch for as many as 180 days.

How impressive is that?

You won’t worry about winding it or having to replace dead batteries.

He is also very conscious of the environment.

This watch would give him a sense of achievement since he will be sending fewer batteries to the landfills.

Decent Water Resistance

As said earlier, he spends quite some time outdoors.

The number of times he has been rained on or had water splash or spill on him are quite often.

It’s in the nature of a construction worker’s job.

With a water resistance of up to 100 m (330 ft), this timepiece should handle the rain, spills, moisture, sweat, and other liquids well.

It comprises airtight sealing that won’t allow water or moisture in.

The materials will also not corrode, rust or fade.

While it puts up with snorkeling, showering, taking a bath and swimming well, I wouldn’t recommend this watch for deep-sea or scuba diving.

Overall Consumer Reviews

Many consumers give this watch a plus for being sturdy, durable, elegant, and relatively lightweight.

They further say that it has a nice dial and the Eco-drive is very effective.

However, a good number complain that the water resistance isn’t the greatest hence not a very safe choice for extreme diving.

But that’s a different story for a different type of watch, right?

As you can see, this is definitely a watch worth buying.

I love the fact that it’s made from titanium.

It is tough, durable and also resistant to rust, corrosion, and fading.

It’s also lighter than stainless steel and maintains its elegance for a long period.

The display and clarity of the watch are pretty good even in the dimly-lit surrounding.

This is a timepiece that’s worth every penny.
