Watch Workshop: Changing the battery in a Nautica NST-15 watch

 I recently revived my old Nautica NST-15 watch with a new battery. The watch has a bright yellow strap that is perfect for summer. It also has an innovative retrograde calendar that runs  counterclockwise along a date track on the interior portion of the dial. It's pretty cool, but I have to set it properly.

Removing the Nautica NST-15 Caseback

Removing the caseback was easy using a caseback removal tool. I have a tool like the one shown below.  It's available via my Amazon affiliate link here. You just adjust the blue tool to fit the indents on the case and unscrew it in a counterclockwise direction.

The caseback reveals that the watch is made for Nautica by Timex. It's a minor factoid that I'll remember.

Replacing the Watch Battery

The watch is powered by a Miyota 2353 No Jewel Movement that has an accuracy of +/- 20 seconds per month. It uses a standard 377 (SR626SW) battery that is pretty easy to replace. For replacement batteries, check out my battery selection page.

When changing the battery there are a couple of metal pieces that can ever so slightly be pushed aside to release the battery. I think I was able to slightly move the piece on the right that lies atop the battery. The tiniest bit of movement was sufficient.

Wristwatch Review: The Nautica Unisex N14663G NST 15 Date Watch with Textured Yellow Band

Spring is coming! But, to hasten its arrival, my wife recently bought me a very bright Nautica watch. It's the Nautica Unisex NST 15 Date Watch (Model N14663G) with a bright yellow band.

I've long admired Nautica watches because they have innovative designs and solid construction.  Unfortunately, one of my co-workers wears awesome Nautica watches all the time and I don't want to steal his style.  No one likes a copycat.   

Style. I like this watch dial design because it combines retro sensibilities and innovation.  I think that this Nautica watch looks like a dive watch from the early 1970s.  It is well proportioned with a 45 millimeter diameter case that is just over 13 millimeters thick.  But, the inner part of the dial contains a very cool retro-grade calendar.  In the first picture, notice the orange arrow pointing to the 5th day of the month at 10 o'clock.  How cool is that?  However, I must confess that I can't read the tiny date numerals at all.  That's what an old guy gets for trying to be hip.  The 20 millimeter wide yellow band is quite bright and takes some getting used to.  However, there is a similar Nautica watch with a dark blue band.

Construction.  The Nautica NST 15 Date Watch is solidly constructed with a stainless steel case, bezel and case back.  A screw down crown helps ensure 100 meters of water resistance.  According to Amazon ad copy, the watch is suitable for snorkeling or swimming, but not diving.  That's too bad because the watch also has a unidirectional rotating bezel.  I love those for the functionality of being able to measure elapsed time.  The dial is protected by a mineral crystal for scratch resistance.  Finally, beneath the beautiful exterior lurks an ever reliable Japanese quartz movement.   

Price. My wife got a phenomenal deal on this watch at our local TJ Maxx / HomeGoods store.  However, the prices on Amazon are quite good. Overall, I highly recommend the Nautica NST 15 Date Watch.  This is a watch deal that I'm excited about. It's a great looking watch and it's a great watch value for the money.
