Question 1

Which Seiko should I buy first?

Accepted Answer

For an everyday watch, start with a Seiko 5 Sports SRPD55 or a Prospex Turtle SRPE93; both run the tough 4R36 caliber. If you want a more refined feel and a 72-hour power reserve, the current 6R55-powered Prospex Alpinist is the logical next step up.

Question 2

Do Seiko watches hold their value?

Accepted Answer

Most everyday Seiko 5 and 4R-series pieces do not fully hold value; they are bought for enjoyment, not investment. On the secondary market, the Prospex divers and limited editions hold up best. Keep expectations realistic: Seiko gives you a lot of watch for the money.

Question 3

How often does a Seiko automatic need service, and what does it cost?

Accepted Answer

Seiko recommends maintenance every two to three years, though the 4R movements run far longer in practice. A full service on the 6Rxx movements costs around $260 in the US. Since parts are plentiful, a trusted independent watchmaker can often service them for less.

Question 4

What is the difference between the 4R36 and 6R55 calibers?

Accepted Answer

The 4R36 is the entry caliber: 24 jewels, roughly 41 hours of power reserve, with day and date. The current Alpinist's 6R55 is more refined, offering a 72-hour reserve. The latter keeps running if you set it down for a long weekend.

Question 5

Where should I buy a Seiko, and are there waitlists?

Accepted Answer

No, there are no waitlists. Seiko models are easy to find at authorized dealers and major online platforms, and street prices routinely land below retail. Buy from an authorized dealer for warranty and authenticity; if buying used, always check the movement and case condition first.
