Product Identity
The Seiko SSB345 is a men's quartz chronograph with a 44mm stainless steel case and matching bracelet. A blue dial with orange accents and three subdials provides stopwatch function up to 60 minutes in 1/5-second increments plus a 24-hour register. Mineral crystal and 100m water resistance complete the specification.
Compatibility Check
Verify that a 44mm case diameter and 13mm thickness suit your wrist and that a 21mm bracelet width fits your preferred strap options. The deployment clasp with push button requires no tool for adjustment but confirm the fixed bezel and mineral crystal meet your durability expectations. Quartz movement needs no winding but will require a battery change at service intervals.
Buyer Fit
This watch suits buyers who want a dress-formal chronograph with tachymeter bezel and date display between 4 and 5 o'clock. It is not for shoppers needing automatic or mechanical movement, sapphire crystal, or water resistance beyond 100m. Buyers requiring a smaller case diameter, lighter titanium construction, or smartwatch connectivity should look elsewhere.

Questions about this item
Does the SSB345 come with the stainless steel bracelet and deployment clasp already fitted, or must I buy a strap separately?
The brushed-polished stainless steel case and 21mm bracelet with deployment clasp are supplied together; no separate strap is required.
Should I choose the 44mm case or the 43.9mm specification when deciding if the SSB345 fits my wrist?
Both figures describe the same watch — the case diameter is 44mm, with the manufacturer also noting 43.9mm for precision.
What does the 100m water-resistance rating mean for daily wear with the SSB345?
It is rated for swimming and surface snorkelling, but not for scuba diving; the screw-down crown and mineral crystal maintain the seal.
