The Orange Monster is a true men's dive watch.  It is attractive and has a decent size.  The watch is bigger than the&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Citizen-Men-s-Eco-Drive/dp/B000EQS1RO/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Citizen Men's Eco-Drive</a>

PROS:
Unidirectional bezel with luminous zero position on the bezel.  The bezel markings are embedded not printed on - this watch is built to last!

The bezel has 120 indents so you can set the bezel to time your dive to the half minute.

Really bright luminous hands - including a luminous sweep second hand.

Orange dial for greater visibility underwater in poor light.

Day and date display at the 3 o'clock position.

Day setting in English or Spanish.  WEEDKDAYS in black, SAT in blue and SUN in red, DAY in black).

Scratch-resistant Hardlex crystal - curved to magnify the dial.  Even the day and date is visible underwater!
The bezel is higher than the Hardlex crystal glass reducing the possibility of scratches.

The large screw down crown is at the four o' clock position.  In this position, the crown never presses into my wrist when I move my hands upwards). The Orange Monster's large crown is much easier to manipulate than the&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Citizen-Men-s-Eco-Drive/dp/B000EQS1RO/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Citizen Men's Eco-Drive</a>&nbsp;- also a great dive watch.

This is an Automatic Movement watch - it never requires a battery.  The watch winds itself with the natural motion of my wrist.  Now that's eco-friendly!

High quality Seiko stainless steel band's fold over clasp with safety keeps this Orange Monster secure on your wrist.

Stainless steel band has an easy to use, fold-out diver's wetsuit extension.

CONS:
Automatic watches being mechanical are never as accurate as a quartz movement - they gain time when it's hot and run slow as it gets colder.  When compared to other automatic winding watches, the Orange Monster is fairly accurate - approx ten seconds off per day.  This works for me.  However, if you need greater accuracy, then I recommend the&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Seiko-Men-s-SNDA63-Diver-Chronograph-Watch/dp/B001OC9B44/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Seiko Men's SNDA63 Diver Chronograph Watch</a>

The Seiko Orange Monster is an attractive Automatic Dive watch at an affordable price - Definitely 5 STARS!

RECOMMENDATION:
If you wear your Seiko Orange Monster dive watch every day, no problem ... once on your wrist, it winds automatically.  However, occasional users or watch collectors may wish to invest in a watch winder.
I bought the&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Diplomat-Burl-Wood-Watch-Winder/dp/B002ZB87ZC/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Diplomat Burl Wood Watch Winder</a>&nbsp;since this model can be set to rotate both clockwise and anticlockwise automatically.
